Using the Law of Electrical Power, how is power calculated?

Power in an electrical circuit is calculated using the formula that relates voltage (V), current (A), and power (W). The correct calculation of electrical power is determined by multiplying the voltage across the circuit by the current flowing through it. This relationship is expressed in the formula W = V x A, meaning that the power (W) is equal to the voltage (V) multiplied by the current (A).

This formula is derived from the definitions of voltage, current, and power in electrical systems, where voltage represents the electric potential difference, current represents the flow of electric charge, and power measures the rate at which electrical energy is consumed or generated. Understanding this relationship is crucial because it helps in designing and analyzing electrical circuits, ensuring that devices work efficiently and safely.

Options that provide different relationships, such as division or incorrect multiplications, do not represent the accurate calculation of power in an electrical context. Therefore, they are not valid in this scenario.
