You are given a number of 10 ohm resistors, each capable of dissopating only 1 w without being destroyed. What is the minimum number of such resistors that you need to combine in series or parrallel to make a 10 ohm resistance that is capable of dissipating at least 5w? Hmm i know the answer...

well i figured out the milken experient but for that other charge one all my charges end up canceling out still i don't quite get it :confused: why can't i set them equal to each other?

Thx for the help guys, I understand charges and Columbs law but i still don't see how it applys to electric fields :confused: For example: Two point charges q1= -5q and q2= +2q are separated by distance d. Locate the point (or points) at which the electirc field due to the charges is...

Hi i am in ap physics and we just finished the electric charges and electric fields chapter but i am completely clueless. I haven't been keeping up with the problems and haven't been to a lot of classes and now it has come back to haunt me. Any good sites out there or can anyone answer some of...
