Which statement describes an ac generator?
it uses a commutator that causes current to alternate.

it produces current that flows in one direction.

it produces current that continuously reverses direction.

Explanation :

An AC generator consists of the alternating voltage source, magnet, slip rings, and brushes. AC current changes the direction of current periodically.

AC generator is used to produce emf. On the application of alternating current, the magnetic flux that is linked with the coil changes and hence the coil rotates continuously.

So, the correct statement that describes an AC generator is (d) " It produces the current that continuously reverses direction ".

correct it is c.) b b

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
