If the capacitor of a single-phase motor is short-circuited_________?
Correct answer: A. the motor will not start
- A. the motor will not start
- B. the motor will run
- C. the motor will run in reverse direction
- D. the motor will run in the same direction at reduced r.p.m
Explanation
Short-circuiting the capacitor removes the phase difference between the main and auxiliary winding currents, so the starting torque is lost. The auxiliary winding may also draw excessive current, making the motor fail to start safely.
