I'm good at learning random stuff...Schrodingerscat wrote:I'd actually consider finding online materials from a college circuit analysis course if you want a thorough preparation in that part. I went through the first third or so of MITx 6.002x which I think definitely helped (this problem is partially based on one of the assignments from that class). You might also have better success going general physics level first as well. You will likely still need to learn other random basic stuff on your own either way though.

This is a guess, but a load of 2000 ohms would be the most efficient? And a efficiency of 73% or 76%?
