What will happen to a single-phase motor when its capacitor is short-circuited | Induction Motor MCQ#50

What will happen to a single-phase motor if capacitor of motor is short-circuited:

1. The motor will burn right away
2. The motor will not start
3. The motor will run in the reverse direction
4. The motor will run at reduced RPM

Correct answer: 2. The motor will not start

If capacitor of a single phase motor is short circuited, the motor will not start.

A single phase motor not self-starting. Rather the capacitor helps the motor in starting. Now if the capacitor is short circuited, then, there will be no starting torque and the motor will not start.
