Multiple Choice

The voltage tolerance of a standard electric motor is _____.

Voltage tolerance is the range around the rated voltage that a motor can operate at safely. For a standard motor, this tolerance is typically ±10%, meaning the supply voltage can be 10% higher or 10% lower than the nameplate voltage. This bidirectional tolerance reflects real-world variations in electrical networks while still keeping the motor operating reliably. The other options either imply only one-direction deviation or no deviation at all, which isn’t realistic for most power systems. Staying within this ±10% range helps prevent issues like reduced torque or overheating that can occur when voltage is outside the tolerance.
