Let's talk about Computers (or Electricity)

Hey, here's something political and electrical for you. How do you feel about our failures to research next generation fusion reactors, and instead focus on subsidizing solar and wind?

Oh yeah, voltage would be kinda hard to answer, because I'd have to know the resistance of your balls (ask me out first). I can say that the aforementioned amount of current (10-80mA) would be in the range of enough to work

Here's a more political question then: How often do older individuals seem as capable as younger individuals at understanding electrics? Is it like the internet, where older people are less likely to truly understand? What might this say about older lawmakers trying to impede technological progress?

Induction heaters work like a transformer: A magnetic field from one component induces a current in another. The current in the other thing makes heat because of the resistance of the material

Because encryption is hard math, and computers have a hard time dividing but an easy time multiplying. If we could make division easy, security would be lost (sorry answering all these fast will come back if time)

Personally I feel that alternative energy investment now could smooth out the transfer we'll eventually have to make. Every alternative has problems, but we can't fix 'em if we don't have funding to try

>How do you feel about our failures to research harmonic wind energy?

There is this stigma in science to try to engineer anything new. Windmills are 1000 year old tech, there has been no huge leap forward in the power source. Why is that? Because fuckers who have good ideas don't get funding over fuckers who rely existing tech.

In my experience, at this point in time older people are more likely to actually understand electricity. Younger people just.... take it for granted a little too much, where as older people in the field have the experience to have understood more of the complexities beyond "hey, I get ohms, I'm a genius!"

Great question. When I see older people that understand Electricity or computers, it's because they were brought up on them. I think that lawmakers get scared over change, and see it as change because the majority of them don't understand how these systems work like we do

Couldn't agree with you more. This summarizes just about all EE and CE in sophomore classes

Alright, honest question.
It was extremely windy yesterday, lights flickered a few times.
Was playing Kingdom Come Deliverance and it crashed, the error code is commonly attributed to a bad psu or ram.
Is it impossible that a small surge could crash a game but not the entire system?

Thanks Mang, I hope you can get back and give your thoughts or a more in depth answer.

I'm not entirely familiar with harmonic wind energy, but that's likely part of the problem you're indicating. While matter does *slightly* exhibit wave motion, it doesn't to the extent that it can harmonize. Harmonic probably doesn't have to do with quantum mechanics, let me check out what this is . . .

Does that mean that the coil that is inducing the current in another piece of metal is actually magnetic from the electromagnet?

Yes, but unlikely. I don't know how windows handles power surges, but enough volts to the right pins of an ethernet connection can make computers do some screwy stuff. Great analysis on your part, btw

What is electricity?
Give me your best answer.

Yes, it is. The coil is technically an electromagnet. You're pretty bright catching on that quick, lots of college kids can't get this stuff.

Most likely, there were branches touching lines and such, but the grid smoothed it enough for you only to see a flicker. Your computer/game system notices flickers several orders of magnitude faster than you can, or even high harmonics, and will be affected.

I know the current generation of turbines introduces higher harmonics onto the grid, but I'm not sure what you are referring to with "harmonic wind energy"

Generally when people talk about electricity, they're talking about current. Current is the movement of charge (a number of electrons) over time. We (basically) wouldn't be able to know about voltage or resistance if charges didn't move, so I'd say that electricity is current (the movement of electrons).

Thanks. For now I'll just assume it was a surge unless it happens again.

I am a biology educator and have rudimentary knowledge of all of the sciences. Physics is the one I have the most trouble with, but I can definitely grasp the basics. Thanks for your help!

Yeah, all generators produce harmonics, which is bad for efficiency. Think of it as being like an echo. If you want to produce usable sounds that make sense, you don't want an echo in the background

electricity is a social construct!

It's interesting if that's what happened because like I said, there was no system crash like a bsod, just the game crashing. I looked up the error code and I hope it was just a surge because I can't afford to replace anything right now.

No problem! Glad to see other people expanding their knowledge bases

did you know there are actually infinite different kinds of electricity. its a spectrum

Lol, I wish. That'd make getting shocked so much easier.
>is shocked
>No, you're not real
>electricity goes away cause isn't real

Yeah, the spectrum of electromagnetic energy goes on for a long way. Those are photons, though, and people generally call the movement of electrons electricity. You are right that electrons exhibit wave motion characteristics too, though.

feminine penises are social constructs. are you saying that they will just disapper too?

V x I = ?
What's the answer OP

If you believe something exists primarily or only in the minds of people, then it would make sense to be able to 'will' it away.

of course i'm right. i'm a scientist with a bachelor's degree in mechanics

Real Power

It was likely just a power flux resulting in one or two bad bits, that's all it takes if it's a critical one. People overestimate the amount of errors it takes to crash things. Processors are now on the size where single cosmic rays in the wrong place can fuck with them.
science.howstuffworks.com/cosmic-rays-crash-electronics.htm

Real power, or consumed power, is also equal it I^2 * R (from V=IR substitution)

And that is why my boss has VLT AMP as the licence plate of his BMW

hi f
care, this thread glows.

My apologies, I'm an EE student, so I've been taught with emphasis on different aspects of science (plus I've not graduated, so yeah)

>Because fuckers who have good ideas don't get funding

The current patent system is used to steal new technology and keep it away from the public, don't think nobody is inventing anything in their own workshop or lab on modest means

That's sick! Too bad I'll have to come up with a different one though. At least there's lots to choose from, like KVL-KCL

do you know about the jews yet?

>a thread about electricity glows

Did you forget your carlos.jpg?

also, something that does glow

I would agree that sharing information and technology is a good thing. You can see a lot of cool innovation in programming by individuals, but no cutting-edge individual-operated high-voltage labs (for now!)

Oh yeah, even if I'd only been on here for long enough to post this I'd know

meant for

What is the fastest diffusing ionic conductor solution for a p-type organic electrochemical transistor to improve its transconductivity?

Cool, it certainly does glow. Probably some pretty high current in that line

Very through question, but sadly my physical electronics class doesn't cover organic transistors. They sound hugely interesting though. Do you know what kind of drawbacks they have? I'd be interested to learn about them.

Somewhere between 30 and 60A, I don't recall. 1kV though.

In what way is human logic different from computer logic- setting aside the physical process?

Correct me if I'm wrong, but doesn't improving conductivity in a semiconductor require doping? I wasn't sure organic ones used doping too, but even if it was a silicon transistor that's kind of a chemical question. I just know that the doping material needs to provide some electrons and have them bound loosely in the outermost shell

I do think people who invent things and better all of our lives deserve to be rich on one hand though, it's just a bitch how patents are classified/shelved.

They're more experienced, my grandfather had his own radio station, my mom got a certificate in electronics. I think it is because back then electronics weren't so disposable. And now that everything is tiny, surface mount stuff with lead free solder it's a lot harder to repair specific components

There are theories that there is no difference aside from the physical means. Some neuroscientists say that neurons work almost exactly like semiconductors, and make one decision, and process one 'bit,' at a time. I guess that the difference is that computer logic has a well defined bit, and is synchronous (obeys a clock) and our logic doesn't have a well-defined bit, and is asynchronous

Human logic and computer logic are one and the same, computers are human inventions after all. the difference is, most human decisions, even the logically based ones, are not reached using only logic, but instead logic, intuition, emotion, experience, estimation, and any other combination of factors, up to and not the least of which is, "what did I eat for lunch today?"

I appreciate the sentiment, and agree. I plan to help some people out, but I'd hate keeping people from using my discoveries (If I can make any good ones)

I would agree that the move towards Integrated Circuits has harmed the ability to easily start working with electricity, but thankfully some platforms like Arduino are helping to combat that

Trust me, I know. I work on a daily basis with equipment that was first put into operation in the 60s, and with people who have been working with that equipment or equipment like it since before I was born, and every new thing I learn is old news to them. And I'm not particularly young.(by this board's standards)

Just a notice, if I take a long time to reply, I'm fighting the CAPTCHA system and their crosswalks and redlights

>Do you know what kind of drawbacks they have?
Yes. They have a time delay between switching modes (depletion, off, accumulation) due to the ionic conductor solution having to diffuse into the organic conductor channel to alter its conductivity by temporary de-doping. It also doesn't handle extremely small or extremely large currents, but has a huge transconductance gain. They have the advantage of being biocompatible, flexible, and 3d printable.

For solid transistors like semiconductor based junctions, yes, doping is how you change the conductivity in the fabrication step. Electrochemical transistors (organic or not) have a liquid dispersion of semiconducting polymer chains, having both ionic flux and electrical flow.

But it is amazing, I was considering the human eye as a band-pass filter composed of many band-pass filters. The bandwidth is the visible light spectrum, there are photoreceptor cells sensitive to different wavelengths of lights, which are in their own way attenuating sigals that they pass while diminishing others. Bees and birds can see ultraviolet light, as though their biological band-pass filter has a higher cutoff frequency.

Definitely, I think about our eyes like that too!

it's evil

Amazing, I'm an advocate for 'em just because we can make them ourselves (3d printing)

almost there OP. V*I gives apparent power in AC, and all power in DC. For real power in AC you still need the phase angle cosine.
t. EE masters student
no i will not fuck off to /sci/, they are boring and only talk about abstract shit.

Electricity? It certainly can be. A 120 bites pretty hard

I have this old textbook (Electronic Fundamentals - Circuits, Devices and Applications by Floyd) and I autistically studied the fundamentals of electricity but forgot a lot. Seems very focused on the practical side and is 1000 pages thick. Would mastering the contents allow me to fix small electronics or do I need more schooling for that?

You're welcome to stay here, I appreciate your expertise. (I found /sci a little boring too)

The gremlins are evil, the gremlins attack any electrical device, no matter how simple, therefor electricity good.

I know you're still in school, but please, never ever say this to anyone in the workforce. 120AC is a pleasant tickle, 240 is a bit of a bitch, and anything over 480 "bites hard"

Hardly just from the book. It helps so you know what's what but fixing electronics is manual labor, probably best skill to pick up would be reading datasheets, the textbook will help decoding that but maybe not that much.

I pulled it up on google, and it looks like the textbook some core EE classes would use. Studying the basics of that book (up to capacitors, inductors, AC, and power) would be excellent for learning electronics repair. Certain devices, like microwaves, require additional complex stuff, but that'd serve you well

The real good part is actually the fact they handle liquids and are biocompatible. You can connect a miniaturised version onto a synapse to get a reading of neuron activity. By picking clever thresholds, you can make a nanoneuroelectronic interface.
(I was thinking more of peripheral neurons, whose synapses we know the function, not brain neurons)

My experience is with transcranial magnetic stimulation, research regarding learning. Basically a small magnetic field can be focused to a region of the brain, focusing it to the motor cortex attenuates the neural response and actually improved learning for motor skills. I took some graduate neuroscience courses and an now in electrical engineering and the similarity between neural networks and circuits is fascinating

Wow, my apologies. You've a higher pain threshold than I

All good bro. I'm more into the oldschool stuff like power than computers. Is your major ECE or just electrical & electronics?
Goddammit I fucking hate semiconductors (but we need them to run all the cool machines we design)

That's amazing, simply amazing. I can't wait to see what we can learn from analyzing our brains in this way.

I'm EE and CE (Electrical and computer engineering double major). Yep, semiconductors can be quirky (kind of a quantum physics joke), lots of my classmates don't care for them. I am partial to all the cool quantum mechanics stuff, though

That sounds like an amazing field to be in, I've only just begun to see the plethora of medical applications EE has

Electromagnetism is where it's at. Over here we're spared the vector calculus torture everyone seems to complain about but my project involves a lot of it so I'm playing catch up. Good luck with your studies mate

The brain isn't the best target for this technology. Its much more complex with many more synapses, and sometimes, synapses form or the brain matter needs to readjust. Inserting one too many OECTs may affect neural development.
On the flip side when used on peripheral nerves you can get external devices (robots, powered exoskeletons, binary human to machine interfaces) to be controlled by specific motions, or to "wirelessly" allow spinal nerves to communicate with the axons in the legs, allowing someone with a severed spinal chord to walk (though they wouldn't feel their legs unless extra sensors were implanted at which point it would be better to replace the limb entirely)

What do you think of 5g? Is it safe?

Thanks, you too. Got an Emag test in 2 days, actually

That makes sense, thank you for explaining it clearly

We used to touch electric fences for fun as kids...we would form a chain of people holding hands to see how many people could feel it. We could all feel it (6 of us). Was that dangerous? The current had to pass straight across all of our bodies from one hand to the other. Also used to put our fingers in light sockets and have someone flip the switch on and off real quick. Didn't hurt, felt just like the electric fence.

Eventually, with a high enough frequency, the signals stop being harmless to organic matter and start vibrating water molecules. Eventually if we kept going up in frequency we'd jsut be microwaving ourselves. I'm not sure if 5 gigaHertz is too high, but maybe.

Nice Pepe, but is he ok? Looks a little shaken up.

Well if you have a very specific and small area of the brain to study, nanoOECTs would give great readings of activity, better than an electro- or magnetoencephalogram, but also much more invasive.
