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) applies to linear circuits or components where the resistance (R) remains constant regardless of the applied voltage or current. For non-linear components, the relationship between V and I is not directly proportional.
Hint
Think about the fundamental relationship between voltage and current that Ohm's law describes.
