Which unit is commonly used to measure electrical power?

The unit commonly used to measure electrical power is the Watt. A Watt is defined as one Joule per second and represents the rate at which electrical energy is transferred by an electric circuit. In practical terms, it quantifies how much work can be done by the electrical energy in a certain amount of time, making it a key measurement in understanding electricity consumption, generator output, and the performance of electrical devices.

In contrast, Joules measure energy, not power, making it a different quantity altogether. Volts measure electric potential, or the force that pushes electric charges through a circuit, while Ohms measure electrical resistance, indicating how much a material opposes the flow of electric current. Thus, the Watt stands out as the appropriate unit for measuring electrical power, reflecting the energy transfer rate in a circuit.
