DC and AC Generators

DC and AC Generators

Multiple Choice

Why DC generator is using split ring?

• so that electrical current can flow in one direction

• so that the electrical current can reverse its direction periodically

Multiple Choice

Which is NOT the difference between DC and AC generator?

• DC generator is using split ring

• AC does not have a commutator

• DC generator exchange carbon brush every half rotation

• Slip rings of AC generator are connected to the different carbon brush
