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 (V=IR) states a linear relationship between voltage and current. It is applicable to linear circuits and components where the resistance remains constant irrespective of the applied voltage or current. Non-linear components (like diodes or transistors) do not strictly obey Ohm's law.
Hint
Consider the relationship between voltage and current that Ohm's law describes.
