Understanding the Concept of Electricity

Among the few inventions that revolutionized the flow of thinking and functioning of mankind is Electricity. We have entered a time where electricity is the necessity for carrying out every small work. No one can deny the contribution of electricity in our day-to-day life and that how everything has changed for better.

Taking a glance at the History of Electricity

History marks the Arabs as the first ones who noticed the effect of electricity among the fish and the lightning effect. Next are the Mediterranean’s, Thales of Miletus who is credited to the work of understanding static electricity i.e. small amount of charge or electricity that can be generated by rubbing two surfaces with positive and negative charges. There are few names that are less famous but are said to be among the contributors such as William Gilbert, Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay, Thomas Browne etc. but the distinguished work on electricity is done by Benjamin Franklin, Michael Faraday, and James Clerk Maxwell. They are the inventors of the electricity laws.

 An Electrical Circuit and its components

Electricity is basically the flow of electrons from one terminal to the other terminal. The electrons are responsible for the flow of electricity because as they move the charge moves. The path on which the electrons move is known as electrical circuits. There are many types of electrical circuits and these circuits can vary from being simple to extremely complex ones depending upon purpose. The electric circuit consists of many electrical components that help in building various types of circuits for various purposes. The common components of a circuit that are used are resistor, capacitor, switch, inductor, transistor, LEDs etc.

 Concepts of Electricity

Most of the components that are used in a circuit are based on the basic concept of electricity. While understanding the concept of electricity one has to understand the two types of electricity i.e. Static and current electricity. Static electricity is the small amount of electricity that is produced by charging positive and negative charges on different surfaces. But current electricity is generated by moving electrons, or it requires an external force to get the electrons moving. Electricity is measured in Watts. Some of the basic things and terms to keep in mind while understanding electricity are units associated with electricity- Volt (V) Ampere (A) Ohm (Ω) Watt (W) Farad (F) Decibel (dB) etc.


Electric current is then classified into alternate and direct current. Alternate current is the changing current that moves in a wave motion. Direct current is constant and more dangerous than alternate current. The basics of the electricity explained above should be understandable to even laymen. Though the concepts are quite simple still they prove out to be completely alien to many of us. But for the electricians, its the basic knowledge just like the back of their hands, if your are interested in knowing more about, you try doing the practical experiment to understand the very nature of electricity but not without the guidance of an able and trained electrician. But don’t try to fix your electrical issues all by yourself, it may prove fatal. You can find a trained electricians in Fitzroy for all such need in
