Which equipment is used to transform mechanical energy into electrical energy?

Correct option is C

A dynamo is a device that converts mechanical energy into electrical energy.
· It does so through the process of electromagnetic induction, where a conductor moving through a magnetic field generates an electric current.
· For example, dynamos are used in bicycle dynamos to generate electricity as the cyclist pedals, in hand-cranked generators for emergency power, and in larger-scale applications such as hydroelectric power plants and wind turbines to generate electricity from flowing water or wind.
