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.
Explain Interrupts of 8085. a) Maskable interrupt b) Vectored interrupt c) Non maskable interrupt d) Hardware interrupt e) Software interrupt
