1.1. All power plants produce electricity All power plants produce electricity with a with a generatorgenerator..

2.2. Power plants have a Power plants have a turbineturbine that is that is connected to the generator. When connected to the generator. When the turbine is turned, it causes the the turbine is turned, it causes the wire loop in the generator to turn. wire loop in the generator to turn. This makes an electric current.This makes an electric current.
