Question

A DC generator is similar to an AC generator except that in

A. DC generators, slip rings produce direct current.
B. DC generators, commutators produce direct current.
C. AC generators, commutators produce alternating current.
D. AC generators, no commutators or slip rings are used.
it is B

Answer 1

The answer would be...B. DC generators, commutators produce direct current. 

Answer 2

B. DC generators, commutators produce direct current.

Step-by-step explanation:

A generator converts mechanical energy to electrical energy. A DC generator produces DC output that is current in single direction. An AC generator produces AC output that is an alternating current.

An AC generator is similar to DC generator except that a commutator or a rectifier is required for producing DC output in DC generator.

A commutator is used mechanically to produce a direct current in a DC generator. It reverses the direction of current in every half cycle producing current in single direction.
