1.	To get the speed of DC motor below the normal speed without wastage of electrical energy we use __________________(a) Ward Leonard control(b) Rheostatic control(c) Any of the Ward Leonard or rheostatic method can be used(d) Not possibleI have been asked this question during an online interview.My question is based upon Ward Leonard Speed Control Method in chapter DC Motors of DC Machines
Answer» The correct option is (a) WARD Leonard control The best EXPLANATION: Ward Leonard METHOD of speed control is most EFFICIENT method of speed control in all aspects. We can get constant torque OPERATION and constant power operations as well, with this method.
