What type of current does a DC motor utilize?

A DC motor operates using direct current (DC), which flows in one constant direction. The utilization of direct current is essential for the functioning of a DC motor because the motion of the motor relies on the magnetic field generated by the direct current passing through the windings. This magnetic field interacts with permanent magnets or additional windings in the motor, producing a rotating motion.

In contrast, alternating current (AC) alternates its direction periodically and is typically not used in DC motors. Impulse current involves surges of current and does not provide the steady flow necessary to maintain motor operation. Hybrid current is not a standard term used in the context of electric motors. Therefore, recognizing that a DC motor fundamentally relies on a steady and unidirectional current supports the understanding that direct current is the correct answer.
