The measurement of electric current can be made using which of the following units?

The measurement of electric current is specifically quantified using the unit known as the ampere. The ampere, often abbreviated as "A," measures the flow of electric charge in a circuit. It represents the amount of charge passing through a point in an electric circuit per unit time.

To provide context, the other options represent different electrical quantities: kilowatt is a unit of power, indicating the rate at which electrical energy is transferred; volt measures electrical potential difference or electromotive force; and joule is a unit of energy, representing the work done when a current of one ampere passes through a resistance of one ohm for one second. Each of these units serves its unique purpose in the field of electricity and electronics, but none measure electric current as directly as the ampere does.
