In order to measure the power taken by a small 220-V 60-Hz single-phase induction motor, it is connected in parallel with a non-inductive resistor across 220-V 60-Hz mains. The currents measured are as follows: resistor current, 5.0 amp; motor current, 6.2 amp; total current, 8.58 amp. Determine power factor of circuit. IT = 6.7 A R motor ? R=? 120 V 60 Hz Lmotor
