Electric current 02/26/16


Have you ever wondered how electricity flows? This phenomena has been labelled by Scientists and Engineers as electric current. When there is a voltage difference within a conductive wire, a flow of electrons occur between this voltage difference. The formula for current is given by the equation I=dqdt, where qis the amount of charge flowing and tis the time. There are two types of current found in Engineering, DC (direct current) and AC (alternating current). In direct current, the flow of electrons is a constant, perpetual unidirectional motion, while in Alternating current it oscillates back and forth.
