Which unit measures the pressure that pushes the flow of electric current through a conductor?

The unit that measures the pressure pushing the flow of electric current through a conductor is the volt. This term specifically refers to the electric potential difference between two points in a circuit, which is what essentially drives electric current. In analogy, just as water pressure is needed to push water through pipes, voltage is what causes electric charges to flow through a conductor, creating an electric current.

In the context of electrical circuits, a higher voltage means that there is a greater electric potential available to push the electrons through the conductor, ultimately resulting in a stronger current flow. Understanding this concept of voltage is fundamental to grasping how electrical systems function, as it relates directly to the behavior of current in relation to resistance as described by Ohm's Law.
