A dynamo is a device used to generate Direct electrical current.

A dynamo is just a D.C. Motor working in reverse. By spinning the motor it generates a direct 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.
