Answer:
Explanation:
This is the equation that defines the power consumed by an electrical circuit. It is normally defined as the product of the voltage applied (V) times the current (I) that runs through it. And in the case of a resistive circuit (resistors in the circuit totaling a certain resistance R), one can use Ohm's law to replace the voltage by the product of the current (I) times the resistance (R), obtaining then the square of the current:
