DC electricity, or direct current electricity, is a type of electrical current that flows in one direction only. This means that the electric charge moves steadily from the negative terminal to the positive terminal of a power source, such as a battery. DC electricity is commonly used in low-voltage applications, like powering small electronic devices and charging batteries. Unlike AC electricity, which alternates direction, DC electricity provides a constant voltage, making it ideal for devices that require a stable power supply. Common examples of DC sources include solar panels and batteries, which convert stored energy into a usable form for various applications.
