WebBoth AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. WebThere are basically four steps involved in making a cell phone charger. First step is stepping down the 220 volts of AC supply into small voltage. Second step involves rectification of AC into DC by using a full wave bridge rectifier. Since the DC voltage obtained in second step, contains AC ripple which is removed using filtration process.
