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? (a) Nothing happens, because the aver- age power does not depend on either the frequency or the rms voltage. (b) The average power doubles because it is proportional to the frequency. (c) The average power triples because it is proportional to the rms volt- age. (d) The average power increases by a factor of 32 5 9 because it is proportional to the square of the rms voltage. (e) The average power increases by a factor of 2X3=6 because it is proportional to the product of the frequency and the rms voltage.
