What does Ohm's Law state?

Ohm's Law is a fundamental principle in electronics and electrical engineering that defines the relationship between voltage, current, and resistance. It states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, provided the temperature remains constant and the material's properties do not change. This relationship can be expressed mathematically as V = IR, where R is the resistance in ohms.

This equation indicates that if you know the current flowing through a circuit and the resistance, you can calculate the voltage. Understanding this relationship is crucial for technicians when troubleshooting electrical circuits, performing calculations, or designing systems, as it allows them to make informed decisions based on how changes in one variable affect the others.

The other options provided represent different interpretations or rearrangements of the relationship among voltage, current, and resistance, but they do not state Ohm's Law in its standard form, which is why the option with V = IR is the most accurate representation of Ohm's Law.
