Download Solution PDFThe correct answer is AC generator will generate a higher voltage.
Key Points
- AC generator converts mechanical energy into AC electrical power.
- A DC generator converts mechanical energy into DC electrical power.
- Some major difference between AC and DC generator are following:-
| AC Generator | DC Generator |
| The current reverses direction periodically. | The current flows only in one direction. |
| The generator (AC ) does not have commutators. | Generators (DC) have commutators to make the current flow in one direction only. |
| Generators (AC ) have slip-rings. | Generators (DC) have commutators. |
| The initial cost of a generator is high. | The initial cost of a DC generator is less. |
| Generators are very efficient as the energy losses are less. | Generators are less efficient due to sparking and other losses like copper, eddy current. |
