Voltage is described as what type of force?

Voltage is described as electromotive force, which refers to the electrical force that drives electric current through a circuit. It represents the potential difference between two points in an electrical system and is measured in volts. Essentially, voltage is the energy per unit charge available to move electrons within a circuit, which is integral for the operation of electrical devices.

This concept is fundamental in understanding electrical circuits and the principles of electricity. Electromotive force not only characterizes the push that causes current to flow but also assists in describing the workings of batteries, generators, and other electrical sources. By recognizing voltage as electromotive force, one can grasp how it influences both the behavior of electrical systems and the performance of cathodic protection, which is crucial for preventing corrosion in pipelines and other infrastructure.
