What does the 'P' in the power formula (P = V × I) represent?

In the power formula ( P = V \times I ), the 'P' stands for power, which is the rate at which electrical energy is transferred by an electric circuit. Power can be expressed in watts, where one watt corresponds to one joule of energy transferred per second.

This formula illustrates the relationship between voltage (V), current (I), and power (P), showing that power is the product of these two components. Understanding this relationship is crucial for anyone working with electrical systems, as it enables the calculation of how much energy a circuit uses or emits over time.

Recognizing the correct representation of power is essential for various applications, such as sizing electrical equipment, ensuring safe operation within the energy limits, and optimizing energy usage in circuits.
