Electricity is one of those things that we take for granted. We turn our lights on and off in the morning, we turn the TV on to watch the news, we make a cup of tea and then drive to work. Our lives are dominated by the necessity of electricity.
But have you ever wondered what electricity ACTUALLY is? Understanding how electricity works and how it’s used might help you to understand the world that we live in that little bit more.
What is Electricity?
Electricity is a set of naturally occurring phenomena which links to the presence and flow of electric charge. If you have a flow of electric charge, you have an electrical current, which is a form of electricity.
One thing that needs to be considered is an electric potential. An electric potential is the amount of energy a point charge has at any point in space. If you have two electric potentials, one at position A and one at position B, the difference in energy between the two is the voltage.
This is important because if an electrical current also has a voltage associated with it then, if it is in a wire, the wire will have electrical energy. Electrical energy is extremely important as this is what is used to operate lights, kettles, TVs, etc. For you to have a cup of tea, the electrical energy travels from the power station, through the National Grid, into your kettle and is then transformed into heat energy which is used to boil your kettle.
Discovery of Electricity
People have known about the idea of electricity for thousands of years, but it wasn’t until the 17th century when English scientist William Gilbert studied electricity and magnetism by investigating static electricity using amber. The most notorious study of electricity came from Benjamin Franklin in the 18th century, where he supposedly attached a metal key to a kite that he flew in a storm. Sparks began to flow from the key to Franklin’s hand, where he concluded that lightning is a form of electricity.
After this, the study of electricity became a hot topic and began to dominate the world. From Alessandro Volta’s first battery and Michael Faraday’s electric motor to the development of the light bulb, DC and AC current and eventually becoming an essential tool of modern life that we know today.
Electricity is one of the most important things in modern society. If we didn’t have electricity, we would live in a dark age. At B & D Electrical, we understand the importance of needing an installation, which is why we put so much effort and care into what we do.
