The power transferred by an electrical device can be calculated using the equation P = IV, involving the multiplication of current and voltage.
The symbol equation used to calculate the power transferred by an electrical device when the potential difference and current are known is P = IV. This equation shows how the power can be determined by multiplying the current (I) by the voltage (V).
For example, in a circuit with a light bulb, if you want to find the power dissipated by the light bulb, you would multiply the voltage drop across the bulb by the current flowing through it.
Understanding this equation is crucial in analyzing power in electrical circuits and devices.
