Question.
The essential difference between an AC generator and a DC generator is that
(1) AC generator has an electromagnet while a DC generator has permanent magnet.
(2) DC generator will generate a higher voltage.
(3) AC generator will generate a higher voltage.
(4) AC generator has slip rings while the DC generator has a commutator.

(2) DC generator will generate a higher voltage.
(3) AC generator will generate a higher voltage.
(4) AC generator has slip rings while the DC generator has a commutator.
solution:
An AC generator has slip rings while a DC generator has split-ring commutator.
Thus,
option (4) is correct.
An AC generator has slip rings while a DC generator has split-ring commutator.
Thus,
option (4) is correct.
