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 split rings while the DC generator has a commutator
Option D. AC generator has an electromagnet while a DC generator has permanent magnet. DC generator will generate a higher voltage. AC generator will generate a higher voltage. AC generator has slip rings while the DC generator has a commutator
