Article: How does a generator work? Print

electricity-generator-300Most metals have electrons that can move around freely. These electrons allow electricity to move through the metal, transmitting electrical energy from one place to another. These metals are called electrical conductors. A generator is a device that is used to move electrons through a conductor to give electric power. It does this by using a magnet that forces electrons to move along a wire at a steady rate while putting pressure on them.

With the help of a generator, the electrons can transmit electric energy from one point to another. The difference in the number of electrons and the pressure that the generator applies is what creates the different electric currents. The generator spins at a certain number of rotations per minute. The number of electrons that move is measured in amps. The pressure is measured in volts. In the United States, the electric current in the power outlets is 120 volts.
