Question

A circuit contains an ac generator and a resistor. What happens to the average power dissipated in the resistor when the frequency is doubled and the rms voltage is tripled? The average power increases by a factor of 2 times 3 = 6 because it is proportional to the product of the frequency and the rms voltage. Nothing happens, because the average power does not depend on either the frequency or the rms voltage. The average power doubles since it is proportional to the frequency. The average power triples because it is proportional to the rms voltage. The average power increases by a factor of 32 = 9 since is proportional to the square of the rms voltage.

Explanation / Answer

The average power increases by a factor of 3^ 2 = 9 .Since isproportional to the square of the rms voltage.
