The electrical device used for converting mechanical energy into electrical energy is called

An electrical generator is an electromechanical device specifically designed to convert mechanical energy into electrical energy [1]. This process typically involves a spinning shaft or rotor, driven by a mechanical source like a turbine or engine, which rotates within a magnetic field to induce an electric current through electromagnetic induction. In contrast, an electric motor performs the exact opposite function, converting electrical energy into mechanical energy. Other devices mentioned in the options serve measurement purposes: a voltmeter is used to measure the potential difference (voltage) between two points in a circuit, while an ammeter is used to measure the rate of flow of electric current in amperes. Therefore, the generator is the correct device for energy conversion from mechanical to electrical forms.
