NEET Physics Ohm's Law MCQ Question
Which of the following statements best defines when a conducting material obeys Ohm's law?
The resistivity of the material remains constant regardless of the applied electric field.
The voltage across the conductor is always zero.
The current flowing through the conductor is always the same.
The resistance of the conductor changes with temperature.
Correct Answer
Detailed Explanation
Ohm's law asserts that a conducting material obeys it when the resistivity does not depend on the magnitude and direction of the applied electric field, as stated in the NCERT context.
