Q. A 75 light bulb is designed to operate with an applied ac voltage of 120 V rms. The bulb is placed in series with an inductor L, and this series combination is then connected to the 60 Hz 240 V voltage source. For bulb to operate properly, determine the necessary value for L. Assume the bulb has resistance R and negligible inductance.
