Ok, so I'm done with my physics courses and have been having crazy ideas for some time. One of em involves capacitors...but we didn't do all that much. We basically just studied spheres and volage equalization as well as C = e0A/d, Q=CV, just the real basics. I'm essentially trying to get a 1 coulomb charge on a circular plate and need to find efficient and controllable means of doing so. I can get pretty highly rated capacitors that at their peak voltage get ~1.6 C of charge...but then I need to know how to calculate the charge flow and equalization when I hook it up to my plates. Any resources you can point me to would be greatly appreciated.

Do you know how to solve the special case of the confluent hypergeometric function of the first kind? It gives the solution to the radial Schrödinger equation in the Coulomb potential (1/r) of a point nucleus.

I would also look at confluent hypergeometric functions of the second kind which give the second linearly independent solution to the confluent hypergeometric differential equation. It is also known as the Kummer's function of the second kind, Tricomi function, or Gordon function. It is denoted by U(a,b,z)

Wonderful, we didn't even touch that:) lol. Looks like I gotta lot of reading to do.

I was just messing around. I wouldn't read up on that if I were you :)

You want to make your own capacitor, or hook up a capacitor to these plates of yours? What's the point of this?

Learning how capacitors work and respond will take a lot of time and math that you may not be familiar with, from LaPlace and Fourier Transforms, phasors, differential equations, or whatever. If you give me more info on exactly what you want to do, I can probably help you out some more.

Since I'm not sure how much physics or electronics you've really had I would pick up a college textbook. Your best bet is an electronics course in the physics dept.

Also, please be carefull. To start you really shouldn't play with large capacitors. I never played with that stuff outside of lab so I'm not going to give you any real advice.

Playing with capacitors is okay. Just make sure they aren't charged to too high a voltage.

One of my professors would say that in college he and his chums would charge capacitors to a decent level (not sure the value, but I think less than 100 volts) and leave them sitting around waiting for someone to pick up and get shocked.

When I was building a small power supply it used a capacitor that charged to about 38 V, and you could touch both sides and nothing would happen. I think 200+ volts can kill you if it crosses you right, but I've had some accidents with house wiring and gotten shocked by the 110 V a few times. No perma..a,kljl;'ao[]hsld..nent damage done.

Voltage doesn't really matter... it's the current that'll kill you. Static discharges are something like 100000 volts IIRC.

Well, voltage and resistance is what determines the amount of current that flows. Being that the resistance of the human body is on the order of several hundred thousand or more ohms, low voltages cause only micro or mili amps to flow through your body, if that. I think that 6 miliamps can kill if if passes directly through your heart, which would take a couple hundred or more volts to get up to.
