Which law states that power is equal to the product of current and voltage?

The statement that power is equal to the product of current and voltage is grounded in the principles outlined by Ohm's Law. According to this law, the relationship between voltage (V), current (I), and resistance (R) is defined by the equation ( V = I \times R ). Building upon this relationship, power (P), which is the rate at which electrical energy is consumed or produced, can be expressed as ( P = V \times I ).

In practical terms, this means that to find the power used by an electrical device, you simply multiply the current flowing through it by the voltage across it. This is fundamental in electrical engineering and physics, as it allows for easy calculation of power in circuits.

Ohm's Law forms the basis for our understanding of electricity and is essential for further analysis in electrical circuits. The other laws mentioned do not specifically describe the relationship between power, voltage, and current in the same manner. Kirchhoff’s Law refers to circuit analysis principles, Faraday’s Law relates to electromagnetic induction, and Newton’s Law pertains to motion and forces, which is outside the scope of electrical power calculations.
