We all knew that trains and buses run by coal and petrol respectively. They run quite fast. But now steam engines and diesel engines are being replaced by electric engines and long distance trains as well as local trains in cities like Mumbai and Calcutta are being run by electric engines. Electrification of more and more railway tracks is being done. Thus, their speed is increased greatly. The journey by such trains becomes smoke free. Trams are used in big cities for local services. They are also run by electricity. Thus, in transport it is being used increasingly.
The telephone and the telegraph are in much use these days. We can now talk easily to a friend or relative who is at a great distance from us. We can communicate our messages with the help of telegraph and fax even to the most distant corner of our country within no time. Indeed, many a business will come to a standstill in the absence of these speedy means of communication. Thanks to electricity which has given us such swift means of communication. The role of television cannot be over emphasized. We can witness all that is happening even on the other side of the globe simultaneously. Satellites have made this possible.
Many diseases are to-day cured by electric treatment. Surgeons will not be able to carry on operations as their instruments and machines are operated by it. X-ray machine which enables the doctor to take the photograph of the
