Hi! You can use the basic power formula, \(P=I^2\ R\). But you can't just use your peak current to get the average power. Think, what's the average power, and at what current is it? Well, power is never negative. The current can go either way and the power will be positive. So, the power is like this:|dw:1374540834226:dw|
