What is the unit of measurement for electrical power?

The unit of measurement for electrical power is the Watt. One Watt is defined as the amount of electrical energy transferred or consumed per second. It is derived from the equation of power which relates voltage (measured in Volts) and current (measured in Amperes) through the formula: Power (W) = Voltage (V) × Current (A).

Understanding electrical power in terms of Watts is crucial because it helps quantify how much energy is being used or produced in an electrical circuit. This measurement is particularly important for applications such as determining the energy consumption of appliances or the output of power generation systems.

The other units mentioned serve different purposes in electrical theory: Ohm measures electrical resistance, Volt measures electrical potential difference, and Ampere measures electrical current. While all of these units are integral to understanding electrical systems, none represent the concept of power in the same way that the Watt does.
