Ohm's Law establishes a fundamental relationship between current, voltage, and resistance in an electrical circuit. The correct answer highlights that voltage (V) is equal to the product of current (I) and resistance (R), expressed in the formula V = IR. This means that for a given resistance, an increase in voltage will result in a increase in current, indicating a directly proportional relationship between voltage and current when resistance is held constant.

Understanding this relationship is crucial for analyzing circuits. For example, if you know the voltage supply and the resistance in a circuit, you can easily calculate the current flowing through the circuit using this formula. Ohm's Law is foundational in electronics and electrical engineering, allowing professionals to design and troubleshoot circuits effectively.

In contrast, the other options do not accurately reflect the relationship as defined by Ohm's Law. Therefore, identifying the accurate formulation reinforces understanding of these fundamental concepts in electronics.
