What is Ohm’s Law?

Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. According to this law, the voltage across a conductor is directly proportional to the current flowing through it, provided the temperature remains constant. The correct formula that represents this relationship is V = I × R, which means that voltage is the product of current and resistance.

This fundamental principle is essential in analyzing and designing electrical circuits, allowing you to calculate how much voltage is required to drive a certain amount of current through a resistor of known resistance. Understanding Ohm's Law is crucial for students in advanced electronics and electrical engineering, as it provides the basis for more complex circuit analysis and design.
