Electricity is the presence and flow of electric charge (electrons) in one direction. Using electricity we can transfer energy in ways that allow us to do common chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word "electricity" is sometimes used to mean "electrical energy". They are not the same thing: electricity is a transmission medium for electrical energy, like sea water is a transmission medium for wave energy. An item which allows electricity to move through it is called a conductor. Copper wires and other metal items are good conductors, allowing electricity to move through them and transmit electrical energy. Plastic is a bad conductor (also called an insulator) and does not allow much electricity to move through it so it will stop the transmission of electrical energy.
Importance of electricityLooking at the present condition, there is no doubt in saying that the modern society is completely dependent on electricity. Electricity has become an indispensable need for the development. It is also a prime essentiality to sustain modern urban life. We are so much dependent on electricity. Our life becomes still when the electricity supply shuts off however small the duration is. Nowadays, everything has become electronic. We have electronic mails, electric tram, electric train, electric bulb, electric fan, electroplating, electric stove, etc. that makes our life a lot comfortable and easier. The more habitual we have become of all these things, the harder it gets to sustain life without it.
Uses of electricity in various fieldsElectricity has completely transformed the way farming has been carried out nowadays. As opposed to the way farming was carried out in earlier days, now the entire process has become mechanized. Electricity has made it easier to distribute the river water to canals and perform irrigation in barren and dry lands.
Electricity has helped people a lot in quick and speedy communication. Wireless telegraphy can be used with electricity. With the help of phones, computer etc. instant communication has become a lot simpler and easier.
Electricity driven machines like washing machine, refrigerator, vacuum cleaners, heaters, coolers, AC’s, has made our daily chores and living hassle free and uncomplicated. We can’t just think life without any of them. They are an essential part of our life. Without electricity, there is no splendor and glamour in celebrations and festivities.
As electricity removed darkness from the streets and roads and is considered to be a boon to modern society. If we don’t care about making its judicious use, then it will get wasted. Our life will again slip back to old primitive days when there was no electricity.
Electricity has brought a revolution in medical science. Leprosy, cancer, and various other fatal ailments can now be easily cured using painless treatment method of exposing to electricity. One of them being X-rays. Modern detection and cure of various ailments are computerized.
Electricity is carried out in performing technical and engineering activities. Whether it is performing welding or developing certain materials, it requires electrical energy to perform these tasks.
