Electricity Innovations
Although the modern electrical service industry did not start until the late 1800s, electricity has fascinated us since our ancestors first witnessed the lightning. The ancient Greeks discovered that rubbing amber produced an electric charge. Electricity is a basic part of nature and is one of our most used forms of energy. It is a secondary energy source that we obtain from the conversion of primary sources such as natural gas, oil, coal and nuclear energy. Many cities and towns were built next to waterfalls that turned water wheels to do work. Before the start of the generation of electricity, kerosene lamps lit the houses, ice boxes were used to keep food cold and the rooms were heated with stoves. The "needs" of today, such as light bulbs, fans, air conditioners and refrigerators, are derived from the ideas of the inventors who lived more than 100 years ago. Many of us are familiar with Benjamin Franklin's famous comet experiment and Thomas Edison's light bulb, but there were many other inventors who contributed greatly to our modern uses of electricity. Some of these inventors simply tried to improve the old ideas and others saw a need and let their curiosity go crazy with each experiment until they discovered something new. Each invention paved the way for the next.
In the mid-seventeenth century, Otto von Guericke, a German physicist, began to experiment with the generation of electricity. In 1670 he invented the first machine to produce electricity in large quantities using a ball of sulfur that turned and held his hand against the ball, charging it with electricity. Others, like Isaac Newton, used this machine later using a glass ball instead of sulfur, and then a cylinder and then a glass plate.
In 1747 Benjamin Franklin began experimenting with electricity and proposed the notion of positive and negative charge. He made his famous comet experiment to prove that lightning was a form of electric shock in 1752. During a thunderstorm, he blew up a kite with a rigid cable pointing upwards attached to the top of the kite and a key attached to the other end of the rope. and leave it hanging near a jar. The rope got wet from the rain and caused sparks from the key to jump into the bottle until the bottle could not handle any more loads. This experiment showed that electricity and lightning are one in the same and that pointed rods conduct electricity better than balls, which leads to Franklin's invention of the lightning rod. From this experiment, the principles of electricity were gradually understood.
In 1800, an Italian professor, Alessandro Volta, invented the voltaic battery that is now called an electric battery or battery. He made a pile of zinc discs, acid or paper soaked in salt and copper, and when he touched both ends he received an electric shock. The volt is named after Volta. Another, that in the first half of the 1800s contributed greatly to our modern uses of electricity, was Michael Faraday. He conducted experiments in electricity and magnetism that led to modern inventions such as the engine, the generator, the telegraph and the telephone. In 1831 he experimented with induction and discovered a way to generate a large amount of electricity at a time. We use its principle of electromagnetic induction to generate electricity today in power plants.
