when the speed of a dc motor increase the armature current

A

Increase

B

decrease

C

Does not change

D

Increase and decreases continuously

Text Solution

Verified by Experts

The correct Answer is:
B

With the increasing speed, `omega` increases. Thus current reduces due to increase in the back e.m.f
Moreover `i=(V-Komega)/(R )`. More `omega` will lead to the lesser current
