The primary difference between an AC generator and a DC generator lies in the mechanism used to collect the induced current. An AC generator uses slip rings, which allow the current to flow out as an alternating current. A DC generator uses a commutator (split rings), which reverses the connection to the external circuit every half rotation, thereby ensuring the current flows in only one direction in the external circuit, producing a direct current.
The basic difference between an AC generator and a DC generator is that
