A capacitor rated for continuous duty in a motor circuit is normally

  • A.a tantalum electrolytic type of small capacitance
  • B.an oil-filled or metallised film type
  • C.an aluminium electrolytic type of large capacitance
  • D.a variable air-dielectric type adjusted at each start

Answer: B

Correct answer: an oil-filled or metallised film type

A capacitor in circuit whenever the motor runs must carry alternating current continuously without heating, and film or oil-filled types are built for it. An electrolytic capacitor would overheat and fail within hours - which is why the two kinds must not be substituted for one another.
