According to Ohm's Law, how is voltage calculated?

Ohm's Law is a fundamental principle in electrical engineering that relates voltage, current, and resistance in an electric circuit. According to this law, voltage is calculated by multiplying current (the flow of electric charge) by resistance (the opposition to that flow). This relationship is expressed mathematically as V = I × R, where V stands for voltage, I for current, and R for resistance.

This equation illustrates that if you know the current flowing through a conductor and the resistance of that conductor, you can easily determine the voltage across it. This principle is essential for analyzing circuits and understanding how various components interact.

While other options reference relationships among electrical quantities, they do not accurately describe voltage calculation as defined by Ohm's Law. Understanding this relationship is crucial for anyone working in electronics or related fields, as it lays the groundwork for circuit design and analysis.
