Question
Ohm's law can be used only to a _________ circuit or component.
Correct Answer
Option D is the correct answer.
Detailed Explanation
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. This relationship (V=IR) holds true for linear components, where resistance is constant regardless of the voltage or current.
Hint
Think about the characteristics of components for which resistance is a constant value.
