Which formula is a representation of Ohm's Law?

Ohm's Law is a fundamental principle in electronics and electrical engineering that defines the relationship between voltage (V), current (I), and resistance (R). The correct representation of Ohm's Law is the formula that relates voltage to current and resistance, expressed as V = I x R.

This formula indicates that the voltage across a conductor is equal to the current flowing through it multiplied by the resistance of that conductor. Understanding this relationship is crucial for analyzing electrical circuits, as it allows professionals to calculate one variable when the other two are known.

In practical applications, this means that if you know the resistance in a circuit and the current flowing, you can easily determine the voltage. This foundational concept is extensively utilized in troubleshooting and designing electrical systems.

Other formulas presented have different meanings and uses in electrical calculations: for example, the formula P = V x I represents the relationship between power (P), voltage, and current, which is relevant for calculating power in circuits but does not represent Ohm’s Law.
