Question

The purpose of a capacitor unit in a vacuum cleaner is to

A. suppress radio-frequency interference.

b. increase the motor starting torque.

C. reduce the voltage applied to the rectifier.

d. eliminate brush arcing.

Answer 1

I'm currently on this section, so I'll provide you with some help. In the appliance study guide on page 64 it states. "A capacitor may be used in a circuit to help remove radio frequency interference."

So the answer in-fact should be A.
