Electrical power sources. Collection of different sources of electrical power. At lower centre are different types of batteries, portable devices that use chemical reactions to store and release electrical energy. At lower left is a dynamo, a device used to convert the energy of mechanical motion into electricity. Behind these is a power supply unit, which is used to convert mains electricity to the required level of electrical current and voltage.
