C)solid-state starting
D)hot-wire starting

Question

Quizplus · Accepted Answer

The relay described in the question is known as a hot-wire starting relay. It uses a resistive wire, often made of nickel-chromium or tungsten, to sense the current flowing through the motor. As the motor starts, the wire heats up and its resistance increases, which opens the relay and removes the starting capacitor from the circuit.
