Two-value capacitor motor finds increased application as compressor motor in small home air-conditioners because_____________?
Correct answer: C. it has low starting as well as running currents at relatively high power factor
- A. it is comparatively cheaper
- B. it has almost non-destructible capacitor
- C. it has low starting as well as running currents at relatively high power factor
- D. it is quiet in operation
Explanation
A two-value capacitor motor uses a large capacitor for starting and a smaller capacitor for running, giving high starting torque with relatively low current and good power factor. These properties suit compressor loads in domestic air-conditioners.
