What is electricity sources?

Answer 1

Sources of electricity are areas of high electric potential. This means that the region/area has a net negative charge i.e. high number of free electrons. Electricity is created when these areas of high potential discharge their electrons into neighboring areas of lower potential because it is by definition the flow of electrons from high to low potentials. Most man-made electricity is created using some form of generator. Generators are devices that convert mechanical energy into electrical. Typically this is done by rotating high powered magnets inside tightly coiled copper wiring. The magnet essentially tears electrons off the copper atoms creating high negative potential within the wire. The resulting flow of electrons out of the generator through wiring to areas of less potential is electricity. In nature we see electricity when high negative potential builds within storm clouds because friction between water droplets tears electrons free. The negatively charged clouds discharge into the ground below in the form of lightening.
