The essential difference in design of the AC generator and a DC generator is that Correct Answer AC Generator has slip rings while DC Generator has a Commutator

Concept:

SI.

No.

 Differentiating property AC Generator DC Generator
1. Definition AC generator is a mechanical device that converts mechanical energy into AC electrical power. DC generator is a mechanical device that converts mechanical energy into DC electrical power.
2. Direction of current In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction.
3. Basic Design In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less. In a DC generator, the coil through which the current flows rotates in a fixed field. The overall design is very simple but construction is complex due to commutators and slips rings.
4. Commutators AC generator does not have commutators. They have slip rings DC generators have commutators to make the current flow in one direction only.
5. Diagram Important Points

The generator converts mechanical energy into electrical energy.
