Question: An electric motor connected to a 120 V 60.0 Hz ac outlet does mechanical work at the rate of 0.100 hp (1 hp = 746
An electric motor connected to a 120 V 60.0 Hz ac outlet does mechanical work at the rate of 0.100 hp (1 hp = 746 W).
(a) If the motor draws an rms current of 0.650A, what is its effective resistance, relative to power transfer?
(b) Is this the same as the resistance of the motor's coils, as measured with an ohmmeter with the motor disconnected from the outlet?
