. A 5 HP, 3-phase induction motor draws a current when connected to 230-V. Determine the current drawn by the motor if the power factor is 0.9 and efficiency of 83%.

3. Two 750 kW alternators operate in parallel. The speed regulation of one machine is 100% to 103 % from full-load to no-load and that of the other is 100% to 104 %. How will the two alternators share a load of 1000 kW ? [464-3 kW; 535-7 kW]

131 A 4-pole, 3-phase induction motor is running at 4% slip at full load. If the speed of the motor is 750 rpm, the supply frequency is: (a) 16 Hz (b) 25 Hz (c) 50 Hz (d) 60 Hz

A 220-volt, single-phase induction motor draws 12 amps of current when operated on a 60-Hz circuit.  The power rating of the motor is 2.244 kW.  Determine the rated power factor:
