What unit is used to measure electric power?

The unit used to measure electric power is Watts. Power in electrical systems is defined as the rate at which energy is transferred or converted. In a circuit, power can be calculated using the formula: Power (P) equals Voltage (V) multiplied by Current (I), represented mathematically as P = VI. Consequently, when you multiply the voltage in volts by the current in amperes, the result is measured in watts, which quantifies the electrical energy being used or produced over time. This makes watts the standard unit for measuring the effectiveness of electrical devices in terms of energy consumption or generation. Understanding this unit is essential, as it helps consumers and engineers analyze how efficiently electrical systems operate.
