What type of current is characterized by the constant direction of flow?

• A. Alternating current
• B. Direct current
• C. Reactive current
• D. Inductive current

Answer: (B)

Direct current is characterized by a constant direction of flow. In a direct current (DC) system, the electric charge flows consistently in one direction, typically from the power source to the load, without reversing. This is in contrast to alternating current (AC), where the flow of electric charge periodically reverses direction. The stability of direction in direct current makes it suitable for devices that require a steady and unidirectional flow of electricity, like batteries and some electronic devices. Understanding the nature of direct current is crucial for applications in nail technology, particularly when considering the use of electrical devices such as nail drills, UV lamps, or any equipment that operates on a DC power supply.
