Does a generator generate DC or AC?
A generator is a device that converts mechanical energy into electrical energy. The type of electrical energy generated depends on the type of generator.
There are two types of generators: AC generators and DC generators ¹.
An AC generator is an electric generator that converts mechanical energy into electrical energy in the form of alternative emf or alternating current. An AC generator works on the principle of “Electromagnetic Induction” ¹.
The electrical current produced by an AC generator reverses direction periodically ¹.
On the other hand, a DC generator is a machine that converts mechanical energy into DC (direct current) electricity. The energy alteration process uses the principle of energetically induced electromotive force ¹. The electrical current produced by a DC generator flows only in one direction ¹.
Therefore, whether a generator produces DC or AC depends on the type of generator.
