Electricity can flow in two different ways; either in direct current (DC) or in alternating current (AC). Electricity is a moving electron through or along a conductor, for instance a wire, which have been connected for energy (Daly, Peckham & AudioGO, 2013). Therefore, the variation between DC and AC is the direction of electron flow. In direct current, the electrons flow in one direction (forward). In alternating current, electrons keep changing directions, sometimes forward and at times backwards (Daly, 2013).
Origins of DC and AC Current
A magnetic field next to a wire can make electrons flow along the wire in one direction, because electrons become
