In which unit is true power measured?

True power is measured in watts. This measurement represents the actual power consumed by an electrical device or circuit to perform useful work, such as lighting a bulb, heating an element, or running a motor. True power takes into account the voltage, current, and power factor (the phase difference between voltage and current) in an AC (alternating current) circuit.

In contrast, amperes quantify electric current, volts measure electric potential difference, and ohms denote electrical resistance. While all these units are essential in understanding electrical systems, only watts specifically convey the concept of power in practical applications, illustrating how much work the electric energy is doing over time. This makes understanding the role of watts critical for any industrial electrician when calculating energy consumption and efficiency in various electrical systems and devices.
