The oldest civilization known to understand electricity was the ancient Greeks because of the electric fish in the Nile River. In the 1600’s William Gilbert an English Physician studied electricity and magnetism; studies were continued by other researchers such as Robert Boyle and Benjamin Franklin. Then by the 1800’s scientist Allesandro Volta had identified a way to harness electricity in a battery format and he had also discovered the chemical reactions that electricity could produce. Volta also invented the first device with a steady current known as the electric battery, and he also created the first transmission of electricity by linking positively-charged and negatively-charged connectors and driving an electric charge through them. …show more content…
How is electricity made? Electricity can be generated in power plants fueled by fossil fuels such as coal. 1. The first step of generating electricity in a power plant is to put coal in to a machine called pulverizer which grinds the coal into a fine powder. 2. The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture to the furnace. 3. The burning coal heats up a boiler creating steam. 4. Steam released from the boiler powers and engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine. 5 The spinning turbine is used to power a generator, a machine that turns mechanical energy into electrical energy. This happens when magnets inside a copper coil in the generator spin. 6. A condenser cools the steam moving through the turbine which and it converts into reusable water. (Source C). (Source D) After that process the power plants send out the electricity through the power lines using a transformer which adds voltage to
