Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

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

it is comparatively cheaper
it has almost non-destructible capacitor
it has low starting as well as running currents at relatively high power factor
it is quiet in operation

22.If a single phase induction motor runs slower than normal, the most likely defect is

worn bearings
short-circuit in the winding
open-circuit in the winding
none of the above

23.Starting winding of a single phase motor of a refrigerator is disconnected from the circuit by means of a

magnetic relay
thermal relay
centrifugal switch
none of the above

24.The capacitors used in single-phase capacitor motors have no

voltage rating
dielectric medium
polarity marking
definite value
