A DC shunt generator delivers 200 A at a terminal voltage of 240 V. The armature resistance and shunt field resistance are 0.01 and 60 2 respectively. The iron and friction losses are 1000 W. Calculate: i. Armature current (1 mark) ii. Electromotive force (Emf) generated. (2 marks) iii. Total copper loss. (2 marks) iv. Power input into the generator (Power output of the prime mover). (2 marks) V. The mechanical efficiency. (2 marks) vi. The electrical efficiency.
