Q. A 230-Vdc shuntmotor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find:
(a) The total input power.
(b) The line current.
(c) If the torque lost due to friction and windage is 7% of the shaft torque, calculate the developed torque.
Q. Consider a 240-V supply feeding a resistive load of 10 kW through wires having a total resistance of R = 0.02 . For the same load, let a 120-V supply be used with a total wire
