What does Ohm's law state in relation to automotive electrical circuits?

Ohm's law is fundamental in understanding the behavior of electrical circuits, including those found in automotive applications. It specifically states that voltage equals current multiplied by resistance. This relationship can be expressed with the formula V = I × R, where V represents voltage, I represents current, and R represents resistance.

In automotive electrical circuits, this law helps technicians diagnose and troubleshoot issues by allowing them to calculate the necessary values based on known measurements. For instance, if a technician knows the resistance of a component and the current flowing through it, they can easily calculate the voltage drop across that component using Ohm's law.

The other options do not accurately represent this essential relationship in electrical circuits. While they may incorporate the terms associated with Ohm's law, only the correct statement captures the precise mathematical relationship established by Ohm's law.
