Q.	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 possible
Answer» A. ward leonard control
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.
