Question

What is special about an AC circuit?

A. Charge moves in a single direction.
B. It has only series or only parallel components.
C. It has both series and parallel components.
D. Charge moves back and forth very quickly.

Answer 1

D. Charge moves back and forth very quickly.

Step-by-step explanation:

As we know that in AC source of voltage there is a current which changes its direction rapidly

The frequency at which current change its direction is known as frequency of AC current.

Also we know that the field induced due to this current will also change its direction as the current will change its direction

So if a charge particle is placed in the field which is due to AC source of EMF then due to frequency change in the direction of EMF the field will also change its directions

Due to change in the direction of EMF the force on the charge particle will change its direction

So the charge motion will be back and forth very quickly

so correct answer will be

D. Charge moves back and forth very quickly.

Answer 2

The answer to this is that the special thing about an AC circuit is that D. Charge moves back and forth very quickly.
