MCQ

Armature current in dc motor will be maximum when

A
Motor has acquired maximum speed
B
Motor has acquired intermediate speed
✓
Motor has just started moving
D
Motor is switched off

✓

Answer

Correct option: C.

Motor has just started moving

c
(c)Motor e.m.f. equation ${E_b} = V - {I_a}{R_a}$

At starting ${E_b} = 0,$ so ${I_a}$will be maximum.
