wattmeters
Electrical consumption indicators
Wattmeters are instruments that measure electrical power in watts.
They work by simultaneously measuring voltage and current in a circuit, then calculating the power being consumed or generated.
Electricians and engineers use wattmeters to monitor energy consumption, test electrical equipment, and verify that circuits are operating within safe parameters.
Modern digital wattmeters can also track power over time, calculate energy costs, and detect inefficiencies in electrical systems.
