The Dynamo converts – (1) Electrical Energy into Mechanical Energy (2) Mechanical Energy into Magnetic Energy (3) None of these (4) Mechanical Energy into Electrical Energy
(4) Mechanical Energy into Electrical Energy Explanation: Dynamo is a device for converting mechanical energy into electrical energy, especially one that produces direct current. It uses electromagnetic principles to convert mechanical rotation into a pulsing direct electric current through the use of a commutator.
