Two-value capacitor motor finds increased application as compressor motor in small home air-conditioners because

The correct answer is: C. it has low starting as well as running currents at relatively high power factor.

A two-value capacitor motor is a type of single-phase induction motor that uses two capacitors, one for starting and one for running. The starting capacitor provides a higher starting torque than a single capacitor, which is necessary for starting a heavy load such as a compressor. The running capacitor provides a higher power factor than a single capacitor, which results in lower energy consumption.

The other options are incorrect for the following reasons:

• Option A is incorrect because a two-value capacitor motor is not necessarily cheaper than other types of motors.
• Option B is incorrect because a two-value capacitor motor does not have an almost non-destructible capacitor. The starting capacitor is typically a high-voltage capacitor that is more susceptible to failure than the running capacitor.
• Option D is incorrect because a two-value capacitor motor is not necessarily quieter in operation than other types of motors. The noise level of a motor depends on a number of factors, including the type of motor, the size of the motor, and the quality of the bearings.
