------------------------------------------------- Electric generator In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. It is analogous to a water pump‚ which causes water to flow (but does not create water). The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling
