How is the type of current that we receive in domestic circuit different from the one that runs a clock?

In domestic circuits, we typically receive alternating current (AC), which periodically reverses direction and is used for powering home appliances and lighting. In contrast, clocks often use direct current (DC), which flows in a single direction, providing a steady and consistent voltage necessary for accurate timekeeping. The difference in current type affects the design and functionality of these devices, as AC is more efficient for long-distance power distribution, while DC is better suited for low-voltage electronics.
