Aparticular 60 hz ac induction motor requires some phase delay to operate properly. the real power is 60 kw under a full load that includes real work, heat, vibration and noise. the motor was designed to operate with an 85% power factor (pf) when fully loaded, because some phase difference between voltage and current is necessary to establish the magnetic field in the motor. compute the motor's effective resistance r (with units) given the real power consumed at 240v ac is 60 kw a) b) to produce a capacitive reactance x-1 ohm, what capacitance would be needed at c) 60 hz? (4 pt) compute the capacitive reactance x that must be added in order to increase the power factor to 100% for 240 v and give units.
