Question 14

Suppose the resistance of the coil in question 13 is 2.5 ohms (the ends of the coil are connected together) and the inductive reactance is negligible at that low frequency of rotation. If mechanical friction is also made negligible, how much mechanical power, on the average, is required to keep the coil rotating?
