What is the unit of electrical power?

• A. Volts
• B. Ohms
• C. Amperes
• D. Watts

Answer: (D)

The unit of electrical power is Watts. Power in an electrical context refers to the rate at which electrical energy is transferred or converted. It quantifies how much energy is used or generated over time.

In electrical systems, power can be calculated using the formula ( P = V \times I ), where ( P ) is power in Watts, ( V ) is voltage in Volts, and ( I ) is current in Amperes. This relationship illustrates how power incorporates both voltage and current, which are fundamental electrical quantities.

Understanding this concept is essential, as it applies to various electrical applications, such as in calculating the energy consumption of appliances or the output of electrical devices. This emphasizes the significance of Watts as the standard unit for measuring electrical power.
