AC (alternating current) and DC (direct current) are two types of electrical currents that are used to power various devices. The main difference between AC and DC current is the direction of flow of electric charge.
-
AC current: In AC current, the flow of electric charge changes direction periodically. This means that the electrons in the circuit flow in one direction and then reverse and flow in the opposite direction. AC current is commonly used in households and businesses to power electrical appliances and is the type of current supplied by power grids.
-
DC current: In DC current, the flow of electric charge is constant and moves in one direction only. This means that the electrons flow consistently in the same direction through the circuit. DC current is commonly used in batteries and electronic devices that require a steady and continuous flow of electricity.
In summary, AC current changes direction periodically, while DC current flows in one direction only. The choice between AC and DC current depends on the specific requirements of the device or system being powered.
