1. A separately excited DC motor has an armature resistance of 3.6 and emf constant of 7 V/(rad/sec). The motor is supplied from 102 V dc source, and it drives a load with torque-speed characteristics: T = 0.1 w, Find the motor operating speed. Hint: neglect the rotational losses and use the power output relation (mechanical issues - electrical output) Write the numerical value for the speed in rad/sec. 2. An electric car with both a gasoline tank and a plug-in connector is classified as:
