Uses of electric power
Most aspects of our lives depend on electric power, where people in industrialized countries use many electrically powered devices every day. One of the most important of these is computer hardware, which uses electrical energy to process information. Computers have changed our lives within our homes, schools, and places of business

Uses of electric power

Household appliance


Electric appliances such as dishwashers, toasters, vacuum cleaners and washing machines provide plenty of time and effort. Electric cookers, microwaves and food processors help prepare meals quickly and easily, and refrigerators and freezers store food. Air conditioners and electric fans cool our homes, while electric heaters provide warmth and hot water. TV, radio, video games, CD burners and video recorders provide entertainment opportunities. We can light the electric from the advantage of the night hours

In industry
Without electricity, modern industry would not have existed. Factories produce many products on assembly lines, using electric-powered conveyor belts and electrical equipment. Manufacturers use electrical devices to adjust product sizes and quality. Barrels, saws, and many small appliances operate with electricity.
Electric motors operated by lifts, winches and other large equipment
TV camera
In communications
Almost all devices used by people in communications work with electricity.
Telephones, televisions, radios, fax machines computer modems all powered by electricity. Communication satellites use electrical energy generated by devices called solar cells to transmit information to all parts of the world. Television and radio signals are electrical signals, as are telephone, computer and fax signals transmitted through thin wire or wire ropes called fiber optics
The electric train
In transportation

Uses of electric power

Electric power provides the ability to move trains and tram cars that carry millions of people to their jobs and home. Most cars use the electric spark of the oil tank that provides the engine's capacity. Electric devices help to reduce the consumption of petroleum engines and fuel pollution of the air. Many control devices operated in aircraft and ships with electricity

In medicine and science
Healthcare workers use many electrical devices to examine patients and conduct medical tests. X-rays and magnetic resonance imaging, for example, enable doctors to see the body's internal organs. Cardiac electrical markers record the precise electrical signals from the heart, helping doctors diagnose heart disease
Scientists in all scientific fields use all electrical devices to conduct research. Microbiologists, for example, use a powerful device called a scanning electron microscope to study the secrets of living cells
Physicists use electrolytic particle accelerators to examine the internal structure of atoms. Large electrically operated telescopes help astronomers study planets, stars and galaxies
