A dynamo is a device which – (1) creates mechanical energy (2) creates electrical energy (3) converts mechanical energy into electrical energy (4) converts electrical energy into mechanical energy

1 Answer

Answer :

(3) converts mechanical energy into electrical energy Explanation: A dynamo is an electrical generator that produces direct current with the use of a commutator.
