Sources of mains electricity

Mains electricity comes from a power station and its current is the alternating current which can either be stepped up or down by a transformer.

A.c is produced when a conductor is rotated in a magnetic field or when a magnetic field is rotated near a conductor.

This method is known as electromagnetic induction. The source of energy for rotating the turbine is the actual source of electrical energy.

Most of the electricity in East Africa is generated from water.
