Michael Faraday discovered the method of producing electricity on a large scale. During his life, however, electricity was not put to commercial use. Now the life of the whole world depends on it. It has been put to countless uses.

Electricity is a wonderful energy. It has changed the world. If our forefathers could visit us today, they would feel they had come to a strange planet indeed. Electricity helps us to send messages from one end of the world to the other. It works our telegrams, cablegrams, and telephones and teleprinters. Indeed, the entire modern transport and communication are electrical.

The radio, the television set, the cinema and a hundred other useful and pleasing things owe their existence to electricity. Electricity cooks our food, irons our clothes, sweeps our floors, cools or warms our halls, lights up our houses and cities and makes the wheels of the world go. Switch off electricity, and you switch off the world.
