Answer Notes

Electrical current is defined as the flow of electrons through a conductive path, such as a wire. This rate of flow is measured in Amperes, commonly abbreviated as 'amps.' A good way to visualize basic electronics is by using a plumbing analogy. If electricity were water flowing through a hose, the current (Amperes) would be the actual volume of water moving past a specific point per second. The other options measure different properties: Volts measure the electrical pressure pushing the current, Ohms measure the resistance restricting the current, and Watts measure the overall power produced.
