Starting circuits generally employ resistors of a lower wattage value than circuits that are intended for speed control.

Question

Quizplus · Accepted Answer

Resistors in starting circuits are used to limit the current flow during the initial stages of operation, when the motor is drawing a high amount of current. Resistors in speed control circuits are used to adjust the speed of the motor by varying the amount of current flowing through the motor. Since starting circuits require a higher current flow than speed control circuits, the resistors used in starting circuits typically have a lower wattage value.
