key term - Electric generators

Definition

Electric generators are devices that convert mechanical energy into electrical energy. They work on the principle of electromagnetic induction, where a coil of wire is rotated in a magnetic field to produce an electric current.

Related terms

Turbines: Turbines are often used in electric generators to convert kinetic energy from water, steam, or wind into mechanical energy.

Alternating current (AC): Electric generators typically produce AC power, which periodically changes direction and is commonly used for household electricity.

Faraday's Law:

This law states that the magnitude of induced electromotive force (EMF) in a circuit is directly proportional to the rate at which magnetic flux changes through it. It forms the basis for understanding how electric generators work.
