AC stands for alternating current and DC stands for direct current. The main difference between AC and DC power lies in the direction in which the electric charge flows. In AC power, the flow of electric charge periodically reverses direction, whereas in DC power, the flow of electric charge is always in one direction. AC power is commonly used in homes and businesses, as it is easily converted to different voltages using transformers. DC power is often used in devices that require a constant and steady supply of electricity, such as batteries and electronic devices.
