What is the measure of electrical current?

The measure of electrical current is best represented in amperes. Current refers to the flow of electric charge through a conductor, and amperes (often abbreviated as "amps") quantify this flow. In practical terms, one ampere is defined as one coulomb of charge passing through a given point in a circuit per second.

Understanding this helps clarify the role of other terms. Volts measure electrical potential or voltage, indicating how much potential energy exists to push electric charges through a circuit. Watts, on the other hand, measure electrical power, which is the rate at which energy is consumed or produced in a circuit, calculated as the product of voltage and current. Finally, ohms measure resistance, which indicates how much a component opposes the flow of current. Each of these units is interconnected in the study of electricity, but amperes specifically measure the actual flow of current, making it the correct answer.
