I was sick and missed a week of school. It was the week we started electricity in physics, so I'm kinda confused about exactly what all the vocabulary means.

Here's how I understand it so far:

Charge: Literally, the amount of electrons an object has to transfer.

Coulomb: A measure of charge.

Current: The strength with which electrons transfer from one object to another. I suppose that if you have 2 objects with the same charge, and you allowed 1 charge to flow through a gold wire, and one charge to flow through an iron wire, then the current through the gold wire would be greater, since gold can lose electrons easier. Is that accurate?

Amp: A measure of current.

Watt: Electrical work.

OHM: A measure of resistors, showing how many volts travel through the resistor per amount of current used.

Volt: I'm lost. In terms of electrons, I really don't know what a volt is. I know how to use volts in formulas to figure out questions, but I don't actually understand what it is. The term "Potential Difference" makes no sense to me. The formula V = W/q doesn't make any sense to me either. W is watts, or work, and q is coulombs, or charge. So that says Volts are just how much work is done per amount of electrons you can transfer. I can't understand in what circumstance a 1 coulomb of charge would do more or less work than in any other circumstance.

Thanks for any help,

Jacob
