What type of current is known for a constant flow in one direction?

The correct answer is Direct Current, which is characterized by a constant flow of electric charge in a single direction. This type of current is commonly used in batteries, where the electrons flow from the negative terminal to the positive terminal, providing a stable and reliable source of electricity for devices like flashlights, cell phones, and electric vehicles.

In contrast, Alternating Current fluctuates in direction and is the type of current delivered to homes and businesses, allowing for efficient power distribution over long distances. Static Current is not a recognized form of current in practical electrical use; rather, it refers to the electric charge that can build up on surfaces and can cause static electricity. Variable Current is not a standard term in electrical terminology, but it may imply changing current levels, which does not fit the definition of a consistent flow in one direction.
