C) rotational torque
D) maximum voltage
Locked Rotor Current
The current drawn by an electric motor when the rotor is not turning and power is applied, typically higher than the running current.
Supply Voltage
The electrical potential difference provided to power an electronic circuit or device.
- Comprehend the fundamental concepts and mechanisms behind the operation of electric induction motors.

Final Answer :
A
Explanation :
When a motor is first energized with the full supply voltage, it will draw the highest current it can draw, which is called the locked rotor current. This current is usually higher than the full load current and can cause damage to the motor if it is allowed to continue for an extended period. Therefore, it is important to use a motor starter or soft starter to limit the inrush current during startup.
