What is the standard electrical unit for measuring power?

The standard electrical unit for measuring power is the watt. Power in electrical terms refers to the rate at which electrical energy is transferred by an electric circuit. It is defined as the product of voltage (volts) and current (amperes). One watt is equivalent to one joule per second, indicating that if one watt of power is used, one joule of energy is consumed in one second.

To further clarify the role of other units: volts measure electrical potential, ohms measure electrical resistance, and amperes measure the flow of electric current. While each of these units is significant in understanding electrical systems, the watt specifically quantifies power, making it the standard unit for this measurement. This distinction makes the watt essential in both theoretical calculations and practical applications related to energy usage and generation in electrical circuits.
