Current is measured in ______.

Current is measured in amperes. Amperes, often just referred to as "amps," quantify the flow of electric charge in a circuit. The flow of electricity represents how many electrons pass through a particular point in the circuit over a given period. This is a fundamental concept in electricity and is crucial for understanding how electrical systems function, particularly in HVACR applications where accurate measurements of current are essential for ensuring equipment operates efficiently and safely.

The other terms refer to different electrical measurements: volts measure electrical potential, ohms measure resistance within a circuit, and watts measure power, which is the rate at which energy is consumed or produced. Knowing the distinction between these measurements is vital for working with electrical systems and troubleshooting potential issues. Understanding that current specifically correlates to the flow of electrons is key to grasping how electrical devices operate within HVACR systems.
