Answer 2

The following best describes alternating current, Charge that jiggles  back and forth very quickly.

What increases or decreases alternating current?

A transformer is a machine that either boosts or reduce the voltage of alternating current.

Step-up transformer rises the voltage of alternating current whereas step-down transformer reduces the voltage of alternating current.

Thus, Alternating current is an electric current that peroidically reverses direction.
