The unit of measurement for electrical power is the watt (W). It is named after James Watt, a Scottish inventor and engineer who made significant contributions to the development of the steam engine. One watt is equivalent to the rate of energy transfer or conversion of one joule per second. In electrical terms, it represents the amount of energy consumed or produced per unit of time. Power is a fundamental quantity in electrical engineering and is commonly used to describe the capacity of devices, appliances, and systems to perform work or generate energy.
