The early days of electricity
The discovery of electricity is one of the greatest accomplishments in human history. Electricity has changed our lives and enabled us to do things we never thought possible before. But, it wasn’t always so easy to harness electricity. In fact, many scientists worked for hundreds of years trying to understand and control electricity before it became a usable power source.
To understand the early days of electricity, we must look back to ancient times when people first started to experiment with electric shocks and currents. Ancient civilizations, such as the Greeks and Romans, were fascinated by the effects of electricity. They noted that electric eels could generate shock and that electric sparks could be created by rubbing animal fur against certain objects. These observations provided the basis for much of the experimentation that followed over the next centuries.
In the 1700s, Benjamin Franklin famously experimented with electricity by flying a kite during a thunderstorm. This experiment showed that lightning was an electrical discharge, and it further spurred people’s curiosity about electricity. Other prominent figures of this era, including Galvani, Volta, and Faraday, continued to conduct experiments and make discoveries about electricity.
These experiments laid the groundwork for the development of electricity as a usable power source. By the late 1800s, electricity had become widespread in homes and businesses, and it has been integral to our lives ever since. The early days of electricity were full of discovery and exploration as people sought to understand this new phenomenon.

How electricity was discovered?
The history of electricity is a long and winding one, with numerous important discoveries leading up to the modern understanding of electricity. The first known observation of electricity dates back to 600 BC when Thales of Miletus noticed that when an amber rod was rubbed against fur, it could attract objects such as feathers. This phenomenon became known as “static electricity” and was studied further by other ancient Greeks.
In 1600, English scientist William Gilbert published De Magnete, which described the results of experiments he conducted using static electricity and magnetism. This was the first time that electricity was studied scientifically, and Gilbert's findings laid the foundation for future discoveries.
In the late 1700s, Alessandro Volta discovered that electricity could be created through chemical reactions between two different metals. This type of electricity is known as "electrochemical electricity" and it was the first time that electricity had been artificially created.
In 1831, Michael Faraday discovered the principles of electromagnetic induction, which led to the invention of electric generators and motors. This discovery was the basis for many subsequent advances in electrical engineering.
In 1873, James Clerk Maxwell developed a mathematical theory to describe electricity and magnetism, which he called Maxwell's equations. This led to the development of radio waves and the transmission of information over long distances.
Finally, in the early 20th century, quantum mechanics was developed and this led to a deeper understanding of how electricity works on a subatomic level. This revolutionized electrical engineering and made possible the invention of modern electronics such as televisions and computers.

The applications of electricity
Electricity has become one of the most important elements of our lives, powering almost every modern convenience and device. The applications of electricity are virtually endless and have changed the way we live, work, and play.
Electricity is used in many areas including lighting, heating and cooling, communications, transportation, medical equipment, computers, entertainment, and household appliances. Lighting has become much more energy efficient thanks to LED lighting which uses very little electricity to produce light.
Electric heating systems are becoming increasingly popular as they offer a cost-effective way to keep your home warm. Communications rely heavily on electricity with devices such as smartphones and tablets relying on it for operation.
Electricity has also changed the way we travel with cars, trains, planes, and other forms of transportation all requiring electricity in some form or another. Medical equipment also relies heavily on electricity with MRI machines and other diagnostic tools being powered by it. Computers are another application of electricity, with almost every computer on the planet using it in some form or another.
Entertainment relies on electricity to power televisions, speakers, and other audio equipment. Finally, household appliances such as vacuum cleaners, microwaves, and washing machines all require electricity for operation.
The applications of electricity are seemingly endless and have changed the way we live for the better. As technology advances, new applications for electricity will continue to be developed, making our lives easier and more efficient.

How electricity has changed over time?
Since its discovery, electricity has changed significantly over time. In the early days of electricity, it was used mostly for lighting, communications, and industrial applications. However, as technology advanced and our knowledge of electricity grew, so did its use.
Today, electricity is used to power nearly every aspect of life. We use it to power our homes, offices, and businesses, providing us with energy to light and heat our spaces, run appliances, and even charge our mobile devices. Electricity also allows us to connect with each other in unprecedented ways, using the Internet to communicate with one another across the world in real-time.
Electricity has also become much more efficient over time. Through advances in technology, we are now able to produce more electricity with less energy input, resulting in more energy-efficient buildings and vehicles that run on electric power. Additionally, renewable energy sources such as solar and wind power have become increasingly popular as people strive to reduce their reliance on fossil fuels.
In the future, experts predict that electricity will continue to evolve, with newer technologies allowing us to produce and use electricity even more efficiently. This could lead to a much greener future, where electricity plays an even greater role in our lives than it does today.
