Key Stage 4
Meaning
An alternator is a device used to generate alternating electrical current.
About Alternators
- Alternators use the generator effect to generate and electrical current.
- Alternators are used in power stations which supply the national grid.
 |
| This diagram shows an alternator which has a moving coil of wire rotating through a magnetic field.
Due to the coil flipping over relative to the magnetic field the direction of the current changes with each half turn of the coil. |
