Answer 1

Difference Between AC and DC

Alternating CurrentDirect CurrentAC can carry and safe to transfer longer distance even between two cities, and maintain the electric power.DC cannot travel for very longer distance. If does, it loses electric power.The rotating magnets cause the change in direction of electric flow.The steady magnetism makes the DC to flow in a single direction.The frequency of AC is depended upon the country. But, generally, the frequency is 50Hz or 60Hz.DC has no frequency of zero frequency.In AC the flow of current changes it direction backward periodically.It flows in a single direction steadily.Electrons in AC keep changing its directions –

Answer 2

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.

AC vs. DC (Alternating Current vs. Direct Current) ... 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. In DC, the electrons flow steadily in a single direction, or "forward."
