Answer: Electricity is the greatest gift of science to mankind. We have reached a point of our civilization when electricity is used for all purposes. Without it, our existence will be impossible. Electricity is a source of energy. It is produced by a battery or a coil of wires or by dynamo machine. It is produced in thermal station and also in hydro-project.

There are various wonders of electricity. The most important of all is electric fan and electric light. These two things have improved our living standard and also efficiency of work. Our houses, roads, offices and shops are lighted. It is difficult and sometimes impossible to work in an office where there is no light and fan.

Students read comfortably in a room which is properly furnished with electric light and fan. Fan is not a luxurious thing. It is necessary to fight heat during summer. Electricity is essential to operate fan in summer and electric heater in winter. In cold winter, electric heaters warm our rooms.

Electricity is a means of communication. Telegraph and telegram device is based on electricity. It is easy send messages to distant places. Telephone also functions due to electricity. Due to this facility, the world has become a familiar place for all. Fax-machine is the latest development. Thus, communication is possible due to electricity. Elect has enabled us to conquer time and space.

After the invention of electricity there has been improvement in railways. Previously, the railway trains i steam engines. At present, electric trains are used in all countries. Electricity is of vital use in industries and factories, electricity no factory can run. Now-a-days, everything is done by electricity. We use grinder-mixture, refrigerators, washing machine and other home appliances at our home. But without electricity these things can not function. Radio and television are gifts of electricity. Cinema is impossible without it.

The most important wonder of electricity is felt in the field of medical science. X-Ray, Scanning, Ultra Sonographer Test, E.C.G., Endoscopy, etc. are the developed devices in the field of medicine and surgery. This is possible due to electricity only. Lunacy and mental disorder can be cured through electric shocks to the patients. Computer functions only when it is supplied with electricity.

In view of the numerous uses of electricity, it is right to say that the present age is the age of electricity.

Answer:

Electricity is the best gift of science to mankind. This is an age of electricity. Electricity is a source of light, heat and other comforts. Right from house lighting to the running of giant factories to streets and parks it is the invisible current that makes these entities run. Electricity supplies all types of energy to man in order to improve his scientific inventions and increase his social amenities.  Heating and cooling processes are also executed by it. All you need to do is just switch on a button and there you have ample power.Electricity is primarily produced from coal and water. It is also produced from other sources like nuclear energy, solar energy, etc. but still production is very less. Efforts are being made to produce more electricity from solar, wind and nuclear sources so that the natural sources can be conserved. Need for ElectricityModern world without electricity is impossible now and it is needed in every sphere of life. Electricity facilitates technological advancement and supports a wide range of products and services that enhance our quality of life and stimulate economic productivity. Thus, demand for power is directly correlated with population and economic growth. Houses, streets, parks, offices, shops, malls, etc. are lighted with electricity. Modern communications and transport are rendered safer, speedier and more comfortable by the introduction of the mobile phones, Internet, the electric train, tram and motor.The introduction of electrical devices has simplified labor in every form in the house, in the office and in the factory. Among domestic services, equipment of every type is functioned more cheaply and efficiently by electricity. Many labor saving and timesaving devices using electrical energy have been introduced, to minimize drudgery at home and office. Radio, television, cooler, heater, washing machine, air conditioners, all depend on electricity. There is no grandeur in festivals and celebrations without electricity. Electricity has brought a great revolution in the field of medical science. It plays an important role in the treatment of diseases by electrotherapy. Electricity has changed the way of farming. In fact it has mechanized farming. It has helped us to distribute the water of the rivers into canals and irrigate dry and barren lands. Without electricity we cannot imagine industrial growth. All types of industries require electricity to function.
