In case starting resistance of a series motor is short circuited, the motor will
-
burn out
-
not start
-
run at very high speed
-
run with excessive speed
C
Correct answer
Explanation
When starting resistance of a series motor is short-circuited, the motor receives full voltage immediately, causing very high current and torque. This excessive torque makes the motor run at dangerously high speeds, which can damage the motor. The starting resistance is meant to limit initial current and prevent this unsafe condition.
