What type of current is indicative of a charge flow that does not reverse direction?

Direct Current (DC) is characterized by a continuous flow of electric charge in a single direction. This means that the electrons move steadily from a negative to a positive terminal without reversing. This consistent direction of flow distinguishes DC from other currents.

In contrast, Alternating Current (AC) frequently changes its direction, oscillating back and forth, which is not the case with DC. Pulsating Current, while it may not reverse direction continuously like AC, does have varying levels of magnitude and can be intermittent, which differs from the steady flow of DC. Steady Current, although it implies a consistent flow, can refer to currents that may not necessarily flow in a singular direction, which is why Direct Current is the most accurate answer in this context. Thus, the defining feature of DC is its unidirectional flow, making it the correct choice.
