Armature current in dc motor will be maximum when

A

Motor has acquired maximum speed

B

Motor has acquired intermediate speed

C

Motor has just strarted moving

D

Moving is switched off

Text Solution

Verified by Experts

The correct Answer is:
C
Motor e.m.f. equation `E_(b)=V-I_(a)R_(a)`
At starting `E_(b)=0`, so `I_(a)` will be maximum.
