What is a major difference between DC and AC in ccircuit?

A major difference between direct current (DC) and alternating current (AC) in a circuit is the direction of flow. DC flows in a constant direction, making it ideal for powering devices like batteries and electronics. In contrast, AC periodically reverses direction, which allows it to efficiently transmit electricity over long distances, making it the standard for power grids. This difference in flow also affects how devices are designed to use each type of current.
