The defining characteristic of direct current is that it flows in one direction only. This unidirectional flow of electric charge is what distinguishes direct current (DC) from alternating current (AC), where the flow of electric charge periodically reverses direction.

In practical terms, direct current is commonly used in a variety of applications, including powering electronic devices, charging batteries, and in various forms of electrical circuits. The stable and constant nature of DC makes it ideal for applications that require a steady voltage, such as low-voltage devices, which is why electronic components are often designed to work with direct current.

Understanding this characteristic is essential for students in the beauty therapy field, especially those using equipment that operates on direct current, as it helps to ensure safety and efficacy in treatments that involve electrical devices.
