The purpose of providing dummy coils in a generator is
A)to reduce eddy current losses
B)to enhance flux density
C)to amplify voltage
D)to provide mechanical balance for the rotor

Question

Quizplus · Accepted Answer

Dummy coils are used in generators primarily to maintain mechanical balance of the rotor, especially in cases where the armature winding does not provide symmetrical loading. This helps in reducing vibrations and ensuring smooth operation of the generator.
