What unit is electrical power measured in?

Electrical power is measured in watts. A watt is defined as one joule of energy transferred per second and is the standard unit for quantifying electric power. The concept of power in electrical systems involves the rate at which electrical energy is converted or transmitted, making the watt an essential unit for understanding electrical performance and consumption.

In an electrical context, power can be calculated using the formula P = VI, where P is power in watts, V is voltage in volts, and I is current in amperes. This relationship highlights how watts quantify the amount of energy used or generated over time in an electrical circuit.

The other units mentioned pertain to different aspects of electrical measurement. Amperes refer to the flow of electric current, volts measure the electric potential difference, and ohms indicate electrical resistance. While these concepts are interconnected in the study of electricity, watts specifically represent the product of voltage and current, making them the appropriate measurement for electrical power.
