WebOct 12, 2024 · ALTERNATING CURRENT or AC is like the water flowing back and forth within the hose many times per second. The water analogy breaks down a little here but AC is easily created by electric generators (also called alternators). Nikola Tesla and George Westinghouse championed AC over DC and they eventually prevailed. WebElectricity flows in two ways: either in an alternating current (AC) or in a direct current (DC). Electricity or "current" is nothing but the movement of electrons through a conductor, like a wire. The difference between AC and DC lies in the direction in which the electrons flow.
