Direct Current (DC) is a type of electrical current that flows in a single direction. It is commonly used in batteries, solar panels, and electronic devices. In DC, the voltage remains constant over time, making it suitable for powering devices that require a steady and stable energy supply. Unlike Alternating Current (AC), which changes direction periodically, DC is straightforward and easy to manage. This characteristic makes it ideal for applications like charging batteries and powering small electronics, such as smartphones and laptops. Overall, DC plays a crucial role in modern technology and energy systems.
