I'll start by apologizing for any incorrect terms. I've learnt all of this in french so a few words may be misspelled or even misused. We just started doing electricity in physics 12. I understand F = kqq/r^2 perfectly, I get that potential (electric?) energy is the same formula, multiplied by r. I can do the problems through guesswork (Well, if Voltage is J/C, and I have work and charge...) but I don't UNDERSTAND why I'm doing these things. It's like flying on autopilot. Basicly what I have trouble understanding is: Conversion from voltage to charge/work. Why does it work? It takes 1 Joule to move 1 C to the position that has 1 V electric potential right? What are the two different type of fields? (There's one that is /r^2 and one that is /r, what is each and how are they used?) Just generally confused here. We have a quiz tomorrow and I don't want to have to do some fancy guesswork (even if it does always work).
