Electricity – One of the Finest Inventions

Spread the love

Can you imagine life without electricity; how will be your daily routine without electricity; are you able to live without electricity?

And the answer is ‘NO’; a big No. We cannot live without electricity as it is our basic need. We use electricity in every step of life as now electricity is a part of our life. It is used for lighting rooms, working fans and domestic appliances like using electric stoves, A/C and more. All these provide comfort to people. In factories, large machines are worked with the help of electricity. Essential items like food, cloth, paper, and many other things are the product of electricity.

We as human being surrounded by technology, innovation, and happiness. Electricity is one of the greatest technological innovations of mankind. It has now become a part of our daily life and one cannot think of a world without electricity. It also becomes a part of modern life as now day trains and vehicles are also running with electricity. 

What is Electricity?

Electricity is a product which can be manufactured. It is not a natural resource which can be found in mine and cannot be collected from nature. Electricity is a form of energy. It is the flow of electrons. All matter is made up of atoms and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are “lost” from an atom, the free movement of these electrons constitutes an electric current. Once the electricity generated then it delivered through copper wires to where it is utilized. Electricity is the flow of electrical power or charges through a conductor.

The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy and wind energy into electrical power. It also referred to as an energy carrier, which means it can be converted to other forms of energy such as mechanical energy or heat. Primary energy sources are renewable or nonrenewable energy, but the electricity we use is neither renewable nor nonrenewable.

Who Discovered Electricity?

Benjamin Franklin discovered Electricity in 1752. Benjamin Franklin had one of the greatest scientists of his time. He was interested in many areas of science, made many discoveries and invented many things. Bifocal glasses also discovered by him. In the mid-1700s, he became interested in electricity. He came up with the idea that electricity had positive and negative elements and that electricity flowed between these elements. He also believed that lightning was a form of this flowing electricity.

In 1752, Franklin conducted his famous kite experiment. To show that lightning was electricity, he flew a kite during a thunderstorm. He tied a metal key to the kite string to conduct the electricity.

Just as he thought, electricity from the storm clouds transferred to the kite and electricity flowed down the string and gave him a shock. He’s lucky that he didn’t get hurt, but he didn’t mind the shock since it proved his idea.

Types of Electricity

Electricity is one of the finest inventions in our lives. Electricity is a concept that many are unfamiliar with. Electricity for such people is to switch the button on, the appliance starts to work, switch the button off and that’s it. The importance is understood when the electricity goes off.

There are two main types of electricity:

Static Electricity: – Static Electricity is nothing but contact between an equal amount of protons and electrons (positively and negatively charged subatomic particles). To make this friction work the particles are supposed to be opposite (+,-). If two same-kind particles are i.e. positive-positive or negative-negative, it would then be called as a ‘Non-friction’. You may have noticed static electricity in daily life like when plastic comb or pen comes in contact or rubbed with a woolen garment, static electricity is generated; plastic comb or pen will attract small pieces of papers.

Dynamic / Current Electricity: – This is the common type of electricity which we use in our homes or factories. Dynamic / Current Electricity is a flow of electric charge across an electrical field. This current is lead through a conductor. The conductors are generally of two types; Good Conductor and bad conductors. Good conductors are the ones which let the electric charge flow through them (Copper wires) and the bad conductors are the ones which resist the electric charge (Wood). The constant flow of electric charge causes the conductor to heat up very often.

There are two types of Dynamic / Current Electricity. AC (Alternating Current) and DC (Direct Current).

This type of electricity results from motion of free electrons from one atom to another, if these free electrons flow in one direction, we call this type as direct current electricity (DC) and if these free electrons change its direction from positive to negative periodically (in the same time interval), we call this type as alternating current electricity (AC).
