The flow of electric current is measured in amperes, often abbreviated as "amps." This unit quantifies the rate of flow of electric charge in a circuit, indicating how much current is moving through a conductor at a given time. The term "ampere" is named after André-Marie Ampère, who is one of the pioneers in the study of electromagnetism. In practical terms, if you think of electric current as the flow of water in a pipe, the amperage would represent the amount of water (or electric charge) flowing through the pipe (or conductor).

Voltage, on the other hand, represents the electrical potential difference that drives the current. Ohm refers to the unit of resistance, indicating how much a material opposes the flow of current. A circuit describes a complete path for the flow of electricity, incorporating elements like power sources, loads, and conductors. Thus, while all these terms are related to the function and behavior of electricity, only "ampere" specifically describes the flow of electric current.
