What is the relationship between voltage, current, and resistance known as?

The relationship between voltage, current, and resistance is known as Ohm's Law. This 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. This relationship can be expressed mathematically as V = I × R.

Ohm's Law is fundamental in electrical engineering and electronics, as it provides a basic understanding of how electric circuits operate. This principle allows engineers and technicians to calculate the necessary values of voltage, current, and resistance when designing circuits or troubleshooting issues. Recognizing this relationship is essential for applying various electrical concepts effectively.

The other options relate to different aspects of electrical theory. The power formula refers to the calculation of electrical power (watts) in a circuit and is derived from Ohm’s Law (Power = Voltage × Current). The energy theorem pertains to the conversion of energy in electrical systems, while Faraday's Law deals with electromagnetic induction and the relationship between electricity and magnetism rather than the direct relationship between voltage, current, and resistance.
