Current is measured in ______.

Current is measured in amperes, which is the standard unit of measurement for electric current. Amperes quantify the flow of electric charge in a circuit, representing how much electric charge passes a point in the circuit per unit of time. In practical terms, when you refer to the current in an electrical system, you are indicating how many coulombs of charge are flowing in one second. Understanding this helps HVACR technicians diagnose and work on electrical systems effectively, as managing current flow is critical to ensuring safe and efficient operation.

The other units mentioned have different applications: volts measure electric potential or voltage, watts measure power (the rate of energy transfer), and ohms measure resistance in a circuit. While all these quantities are interconnected in electrical circuits through Ohm's law, they serve distinct roles and purposes in electrical engineering.
