A resistor is connected to normal 60. Hz, 120. volt AC. How many times a second does the instantaneous dissipated POWER reach a maximum?

Question

Quizplus · Accepted Answer

The instantaneous power dissipated in a resistor connected to an AC source reaches its maximum twice in each cycle of the AC waveform. Since the frequency of the AC is 60 Hz, meaning there are 60 cycles per second, the power reaches its maximum 120 times a second (2 times per cycle * 60 cycles per second).
