Ohm's Law is a fundamental principle in electronics and electrical engineering that relates voltage, current, and resistance in an electrical circuit. The correct formula, which is represented by V = IR, signifies that the voltage (V) across a conductor is equal to the current (I) flowing through it multiplied by the resistance (R) of the conductor. This relationship is crucial for analyzing circuits, as it allows for the calculation of one of these parameters if the other two are known.

Understanding this formula builds a foundation for further study in topics such as circuit analysis, power calculations, and the behavior of electrical components. When applying Ohm's Law, it's important to remember that it holds true for many conductive materials, particularly at a constant temperature and for metallic conductors, which obey this linear relationship effectively.
