A motor starter

A motor having an armature of resistance 2.0 Omega operates on 220 V mains. At full speed, it develops a back emf of 210 V. Find the current in the armature just when the motor is switched on (assuming that no starter is used) and when running at full speed. Also fined the efficiency of the motor at full speed.
