Answer 2

A dynamo is an electrical generator that creates direct current using 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.

Uses:- Dynamos, usually driven by steam engines, were widely used in power stations to generate electricity for industrial and domestic purposes. They have since been replaced by alternators.
