Question

How is a DC generator different from an AC generator?
Options
A It uses a split-ring commutator to reverse connections twice per revolution, producing unidirectional current
Correct Answer
B It uses slip rings
C It has no moving parts
D It produces higher voltage
Correct Answer

Option A is the correct answer.

Detailed Explanation

A DC generator uses a split-ring commutator that reverses the connection to the external circuit every half-cycle, resulting in a unidirectional (but pulsating) current.

Hint

Commutator instead of slip rings.
