Electricity is the flow of electric power or charge. It is the set of physical phenomena associated with the presence and motion of matter that has the property of electric charge.
Production of Electricity

SIMPLE GENERATOR DYNAMO
A voltage is produced when a magnet moves in a coil of wire. Generators induce a current by spinning a wire of wire inside a magnetic field or spinning a magnet inside a coil of wire. As this happens a potential difference is produced between the ends of a coil which causes a current to flow.

THREE-PHASE ELECTRICITY
Three-phase electric power is a common method of alternating current power generation, transmission, and distribution. It is a type of polyphase system.

THERMAL POWER GENERATION
The burning of fuels such as oil, coal, and LNG (liquefied natural gas) fires a boiler to generate high-temperature, high-pressure steam. This steam is used to drive a steam turbine. A generator attached to the steam turbine generates electricity.

STEAM POWER GENERATION
Fuels such as heavy oil, LNG (liquefied natural gas), and coal are burned inside a boiler to generate steam at high temperatures and high pressure. This steam is used to rotate the impeller of the steam turbine. This drives the power generators connected to the turbine that generates electricity. This system has a thermal efficiency of around 42% to 46% and functions as a base-to-middle-load supply.
