Which of the following quantities is measured in Amperes?

The quantity measured in Amperes is current. Amperes, often shortened to "amps," are the unit of measurement for electric current in the International System of Units (SI). Current represents the flow of electric charge through a conductor, such as a wire, and is a fundamental concept in understanding electrical circuits.

When current flows, it indicates how much charge is moving through the circuit over a specific time period. Understanding current is crucial for designing, analyzing, and troubleshooting circuits, as it directly influences other electrical properties like voltage and power.

The other options, such as voltage, power, and resistance, are measured in different units. Voltage is measured in volts, power is measured in watts, and resistance is measured in ohms. Each of these quantities plays a role in electrical systems but is distinct and measured using different units.
