(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In a different RLC circuit the generator provides a voltage V(t) = 120 sin(2π60t) so that the current in the circuit is I(t) = 5 sin(2π60t +Φ). The phase angle Φ is 25° (0.436 radians). What is the maximum power dissipated in this circuit?

2. Relevant equations

P = IV (both rms)

3. The attempt at a solution

I simply took the max voltage and current (120 and 5) and plugged them into the rms & power equations. From that, I got the answer to be 600 watts. However, I know that the answer is going to be decreased by some factor because of the phase angle difference. Should end up being 543.8 watts but I don't know how to get to that answer.
