Key Stage 4
Meaning
A dynamo is a device used to generate Direct electrical current.
About Dynamos
- A dynamo is just a D.C. Motor working in reverse. By spinning the motor it generates a direct current.
- Dynamos use the generator effect to generate and electrical current.
- Dynamos are used simple circuits which charge cells and batteries.
 |
| This diagram shows a dynamo which has a moving coil of wire rotating through a magnetic field.
Due to the split ring commutator the direction of the current remains constant at the output. |
