What electrical measurement indicates the intensity of the flow of electric charge?

Volt
Ampere
Ohm
Watt

The correct answer is: Ampere

The intensity of the flow of electric charge is measured in amperes. This unit specifically quantifies the rate at which electric charge flows through a conductor. When you think of electricity in terms of water, amperes can be likened to the volume of water flowing through a pipe; it tells you how much charge is moving. In terms of the other options, a volt measures the electrical potential difference or the pressure that pushes the charge through the circuit. Ohms represent resistance, indicating how much a material opposes the flow of electric current. Watts are a measure of electrical power, indicating the rate at which work is done or energy is converted, which is a function of both voltage and current. Understanding these distinctions clarifies why the correct answer pertains specifically to the intensity of flow, which is solely defined by amperes.
