generator = a machine for producing electricity

alternating current (AC) = an electric current that changes its direction at regular intervals many times a second direct current (DC) = an electric current that flows in one direction only transformer = a device for reducing or increasing the voltage of an electric power supply, usually to allow a particular piece of electrical equipment to be used potential difference = the difference in the amount of energy that charge carriers have between two points in a circuit. eddy currents = loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field coil = a series of circles formed by winding up a length of rope, wire potential = the difference in voltage between two points in an electric field or circuit fuse = a small wire or device inside a piece of electrical equipment that breaks and stops the current if the flow of electricity is too strong live = (of a wire or device) connected to a source of electrical power neutral = having neither a positive nor a negative electrical charge earth = a wire that connects an electric circuit with the ground and makes it safe See also Parallel Electrical Circuit Power Plants #energy_industry
EFL subset that concentrates more on language in context than on grammar and language structures. It covers topics from accounting or computer science to tourism and business management. "Specific" means the studying through a field that is already known and relevant to a student.
