What does Ohm's Law relate in an electrical circuit?

Ohm's Law is a fundamental principle in electronics that describes the relationship between three key electrical parameters: current, voltage, and resistance. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. This can be mathematically expressed by the formula ( V = I \times R ), where ( V ) is the voltage, ( I ) is the current, and ( R ) is the resistance.

Understanding this relationship is essential for analyzing circuits, designing electrical systems, and troubleshooting issues. Knowledge of how current changes with variations in voltage and resistance allows engineers and technicians to predict circuit behavior and ensure that electrical components operate within their specified limits.

Other options, while they may relate to electrical concepts, do not accurately describe Ohm's Law. For example, power and resistance, energy and time, or charge and capacitance involve different principles and equations that hold significance in other contexts within electronics but do not encapsulate the core intent of Ohm's Law.
