What type of electrical current flows continuously in one direction?

• A. Alternating current
• B. Direct current
• C. Pulsating current
• D. Static current

Answer: (B)

Direct current refers to the type of electrical current that consistently flows in a single direction. This is a fundamental characteristic of direct current, making it distinct from other types of electrical currents. In direct current, the flow of electric charge is steady and does not change direction, which is why it is commonly used in many electronic devices, battery-powered applications, and low-voltage circuits. Alternating current, in contrast, changes direction periodically, typically in a sinusoidal pattern. This allows it to be easily transmitted over long distances but does not provide the steady flow characteristic of direct current. Pulsating current involves variations in the current level, often transitioning between positive and negative values, and therefore does not flow continuously in one direction. Static current, on the other hand, refers to an electrical charge at rest rather than in motion and does not describe a flow of current. Understanding these distinctions is important in the context of electrical systems, as different types of current are used for different applications depending on the required characteristics.
