In the formula for power in an electrical circuit, what does "I" represent?

In the formula for power in an electrical circuit, "I" represents current. Power in an electrical circuit can be calculated using the formula ( P = IV ), where ( P ) is power, ( I ) is current, and ( V ) is voltage. Current refers to the flow of electric charge and is measured in amperes (A).

Understanding this concept is crucial because current determines how much electric charge passes through the circuit over time, which directly affects the power output. For example, if the voltage remains constant and the current increases, the power delivered to the circuit will also increase. This relationship is foundational in both theoretical and practical applications of electricity, helping to analyze how circuits function and how components can be manipulated to achieve desired outcomes.
