The back emf in a DC motor is maximum when,

A

the motor has picked up maximum speed

B

the motor has just started moving

C

the speed of motor is still on increase

D

the motor has just been switched off

Text Solution

Verified by Experts

The correct Answer is:
A
The value of back emf ` , e prop W`. So, back emf is maximum when the moor has picked up the maximum speed.
