Answer #1

Part A.

Average power in ac circuit is given by:

P_avg = I_rms^2*R

Given that: I_rms = 6.00 A

R = 16.0 ohm

So,

P_avg = 6.00^2*16.0

P_avg = 576 W

Part B.

Since we know that:

P_avg = I_rms^2*R

And, I_rms = I_peak/sqrt 2, So

P_peak = (I_peak)^2*R

P_peak = (I_rms*sqrt 2)^2*R

P_peak = 2*P_avg

P_peak = 2*576

P_Peak = 1152 W
