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 linearity implies that the resistance remains constant irrespective of the voltage or current, which is characteristic of linear circuits and components.
Hint
Think about the relationship between voltage and current that Ohm's law describes.
