Which value is NOT a component of Ohm's Law?

Ohm's Law is a fundamental principle in electrical engineering that relates voltage, current, and resistance in a circuit. The law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. Mathematically, it can be expressed as V = I × R.

The components that form the essence of Ohm's Law are voltage, current, and resistance. These three are interrelated, with voltage being the electric potential difference, current being the rate of flow of electric charge, and resistance being the opposition to that flow.

Power, while an important electrical concept, is derived from these three components through the equation P = V × I, which indicates how power is related to voltage and current. However, power itself is not a direct component of Ohm's Law. Instead, it can be calculated based on the relationship defined by Ohm's Law but is not one of its fundamental elements. Therefore, power does not represent a component of Ohm's Law.
