What type of current flows in only one direction?

Direct current is the type of electrical current that flows in a single direction consistently. This unidirectional flow is a characteristic of direct current, making it distinct from other forms of electrical current.

In practical applications, direct current is commonly used in battery-powered devices and electronic circuits. It is crucial for devices that require a stable and constant voltage, as fluctuations can cause malfunctions.

In contrast, alternating current changes direction periodically, creating a wave-like pattern. Pulsating current refers to a type of alternating current that has a varying amplitude but also alternates direction, while inverted current is typically not a standard term used to describe a recognized type of electrical current.
