Electricity is a form of energy involving the flow of electrons. Now-a-days electricity has become quite-common in the world. Everybody sees the wonderful work of electricity. The lights on the streets are lit by the electric current. Electric fans work in the court, high court and office-rooms. Trains and trams are run by the electric power. They even made cars that run off electricity. So, electricity is no longer a strange thing.
Electricity is a basic part of nature and it is one of our most widely used forms of energy. Many cities and towns were built alongside waterfalls (a primary source of mechanical energy) that turned water wheels[->0] to perform work. Before electricity generation began slightly over 100 years ago, houses were lit with kerosene lamps, food was cooled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. About six hundred years back the people of Asia Minor and Greece had a very crude idea of electricity. Beginning with Benjamin Franklin's[->1] experiment with a kite one stormy night in Philadelphia, the principles of electricity gradually became understood. In the mid-1800s, everyone's life changed with the invention of the electric light bulb[->2]. In 1879, electricity had been used in arc lights for outdoor lighting. The light bulb’s invention used electricity to bring indoor lighting to our homes. Despite its great importance in our daily lives, few of us probably stop to think what life would be like without electricity. Like air and water, we tend to take electricity for granted. But we use electricity to do many jobs for us every day, from lighting, heating, and cooling our homes to powering our televisions and computers. Electricity was fairly cheap back then, but the price varied on the amount of usage. After World War 1, the economy became a disaster, so companies would sell electricity for much cheaper and insured better and sufficient quality. Ever since...
