Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...
The shaft from the turbine goes up into the generator. When the water moves across the turbine, it spins, rotating the shaft and, in turn, rotating the copper coils of the generator. As the copper coils spin within the magnets, electricity is produced. Power lines connected to the ...
The earths energy is mainly underground coal and oil, and if you just use that very quickly, we need to save energy. Most of the electricity we use comes from coal, which generates billowing smoke and debris when it burns. That oil USES more fuel, cars, planes use life a lot of plast...
