WebWhat is alternating current (AC)? The flow of electrons through a conductor or wire constitutes the electric current. Current can flow through a conductor in two ways. When a conducting wire is connected to a battery, current flows through it in only one direction. Such a current which flows in one direction only is called direct current (DC). WebDec 17, 2024 · Alternating voltage pushes and pulls the charge backwards and forwards in the 'wire'. it is both the positive and negative pole at different times. This movement of …
