What unit is used to measure the flow of electricity?

The flow of electricity is measured in amperes, often referred to simply as "amps." An ampere quantifies the amount of electric charge passing a point in an electrical circuit per unit time. Specifically, one ampere is equal to one coulomb of charge moving past a point in one second. This unit is foundational in understanding electrical systems, as it relates directly to the quantity of electricity flowing through a circuit.

The other units listed serve different purposes within electrical measurements. A volt measures the electric potential difference, or voltage, between two points in a circuit, indicating how much energy is available to push electric charges through the circuit. A watt is a unit of power, representing the rate of energy transfer or consumption, which is calculated from voltage and current (watts = volts x amps). Kilowatt is simply a larger unit of power (1 kilowatt equals 1,000 watts), commonly used for household energy consumption, but it doesn't measure flow directly like amperes do. Understanding the distinction between these units is crucial in both theoretical applications and practical settings in the field of electrical engineering and utility marketing.
