Q. 4. The essential difference between an AC generator and a DC generator is that
(a) AC generator has an electromagnet while a DC generator has permanent magnet.
(b) DC generator will generate a higher voltage.
(c) AC generator will generate a higher voltage.
(d) AC generator has slip rings while the DC generator has a commutator.
Answers (1)
In DC generator, we have two split rings also known as commutator to prevent the change in direction of the current. while in AC, we want the direction to be changed so we use normal slip rings to transfer current from inside of the generator to outside of the generator. This is the main difference between the AC generator and the DC generator.
Hence, option (d) is the correct option.
