Explanation: A dynamo is a device for converting mechanical energy into electrical energy, esp. one that produces direct current. A dynamo is an electrical generator that produces direct current with the use of a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric- power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. |
