What is the difference between AC and DC current?
Electricity flows in two ways; either in alternating current or AC and in direct current or DC. The word electricity comes from the fact that current is nothing more than moving electrons along a conductor, like a wire, that have been harnessed for energy. Therefore, the difference between AC and DC has to do with the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or “forward.” In AC, electrons keep switching directions, sometimes going “forwards” and then going “backwards.” The power that comes from our wall outlets is AC, the more common, efficient kind. Electricity is a very different energy source than heat or light. In nature, electricity only rarely occurs, in some animals, or with lightning. In the search to create electrical energy, scientists discovered that electrical and magnetic fields are related. A magnetic field near a wire causes electrons to flow in a single direction along the wire because they are repelled and attract
