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 flowing through a conductor between two points is directly proportional to the voltage across the two points. The constant of proportionality is the resistance. This relationship (V = IR) holds true only for linear components or circuits, where the resistance (R) remains constant regardless of the voltage or current.
Hint
Consider the condition for a component to be 'ohmic'.
