What does "Ohm's Law" state?

Ohm's Law is a fundamental principle in electrical engineering and physics that relates voltage, current, and resistance in an electrical circuit. It states that the voltage across a conductor between two points is directly proportional to the current flowing through it, provided the temperature remains constant.

The correct expression for Ohm's Law is Voltage (V) = Current (I) × Resistance (R). This means that if you know the current flowing through a resistor and its resistance, you can calculate the voltage across that resistor. This relationship is crucial for designing and analyzing electrical circuits, as it allows engineers and electricians to determine how much voltage is needed for a given current and resistance.

Understanding this concept is essential for anyone working with electrical systems, as it provides the foundation for analyzing circuits and troubleshooting issues. The other options do not accurately represent the relationship delineated by Ohm's Law, leading to potential misunderstandings about circuit behavior.
