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.

D.Charge moves back and forth very quickly.

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.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
