Q.

The speed of a dc shunt motor supplying a load at its rated speed can be reduced by

  • AConnecting an additional resistance in the armature circuit
  • BConnecting an additional resistance in the field circuit 
  • CIncreasing the applied voltage
  • DAny of the above methods
Correct Answer : (A)

Connecting an additional resistance in the armature circuit
