A capacitor in a motor circuit primarily serves to:
- AStore and release electrical energy to aid in starting or running the motor
- BReduce audible noise in the circuit
- CRegulate operating temperature
- DBoost the battery backup
Correct Answer
Store and release electrical energy to aid in starting or running the motor
Explanation
Motor capacitors store electrical energy and release it as a phase-shifted current to create starting torque (start capacitors) or to improve running efficiency (run capacitors).
