Assertion (A): The starting capacitor of a motor must not be left in circuit.

Reason (R): It is an electrolytic type rated only for intermittent duty.

Select the correct option.

  • A.A is false but R is true, the starting capacitor being left in circuit normally
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A at all
  • D.A is true but R is false, the starting capacitor being rated for continuous duty

Answer: B

Electrolytic construction gives a large capacitance cheaply but cannot carry current for more than a second or two, and the auxiliary winding is equally short-rated. The reason is precisely why the centrifugal switch exists.
