When speed of a DC generator decreases, the armature current
  1. increases
  2. decreases
  3. does not change
  4. increases and decreases continuously

A
increases
B
decreases
C
does not change
D
increases and decreases continuously
Solution
Verified by Toppr

The armature current will increase if the speed of the DC generator start decreasing due to an increase in voltage drop at armature resistance.
