What is the unit of electrical power?

The unit of electrical power is the Watt. Power in electrical systems is defined as the rate at which energy is consumed or produced. One Watt is equivalent to one Joule per second, which means it measures how much energy is transferred or converted per unit of time.

This association is crucial because power can be expressed in various ways, but the standard unit recognized in the International System of Units (SI) is the Watt. The electrical power formula, (P = IV), where (P) stands for power, (I) for current in Amperes, and (V) for voltage in Volts, highlights the importance of the Watt in calculating and understanding electrical systems.

The other units listed — Ohm, Joule, and Volt — serve different purposes. Ohm represents electrical resistance, Joule quantifies energy, and Volt measures electrical potential. Each has its unique role in physics and electrical engineering, but in the context of calculating power, the Watt is the correct and relevant unit.
