What is the electrical unit of power?

The electrical unit of power is the Watt. Power is defined as the rate at which electrical energy is transferred or converted in a circuit, and the Watt quantifies this as one Joule per second. It is a crucial element in understanding how electrical devices consume energy. For instance, when you see a light bulb rated in Watts, it indicates how much energy the bulb uses when operating.

In contrast, a Volt represents electric potential or voltage, an Ohm measures electrical resistance, and an Ampere is the unit of electric current. Each of these units serves a specific purpose in electrical theory and practice, but it is the Watt that specifically measures power within a circuit, making it the correct answer. Understanding power in Watts is essential for tasks such as calculating energy usage and efficiency of electrical devices.
