12) What is the function of a centrifugal switch ?

To disconnect the running winding

To disconnect the starting winding when the motor attains 75% of its rated speed

To disconnect the rotor resistors

None of the above

Answer is:

To disconnect the starting winding when the motor attains 75% of its rated speed

starting the motor

stopping the motor

providing overload protection to the motor

all the above three reasons

Answer is:

ceramic capacitors

mica capacitors

paper or non-polarised electrolytic capacitors

styroflex capacitors

Answer is:

series voltage regulator

tapped field method

centrifugal switch method

any one of the above stated methods

Answer is:
