A DC shunt motor rotating at 1560 RPM is supplied from a 240-V source. The line current supplied to the motor is equal to 27 A. The shunt field resistance of the motor is equal to 120 Ω and the armature resistance is equal to 0.6 Ω. Calculate the following:(a) The armature current of the machine.(b) The back-emf.(c) The output mechanical power and the net torque developed by the motor if its mechanical losses are equal to 280 W.
An abrupt silicon (n i = 10 10 cm -3 ) p-n junction consists of a p-type region containing 10 16 cm -3 acceptors and an n-type region containing 5 x 10 16 cm -3 donors. a)
