NEET Physics Ohm's Law MCQ Question
Which of the following statements regarding Ohm's Law is correct?
Ohm's Law is valid for materials where the resistivity is independent of the electric field.
Ohm's Law applies universally to all conducting devices regardless of their properties.
A diode obeys Ohm's Law across all voltage values.
A resistor exhibits a non-linear I-V relationship at high electric fields.
Correct Answer
Detailed Explanation
Ohm's Law asserts that materials obey it when their resistivity does not depend on the electric field, as mentioned in the context. Options B and C reflect misunderstandings about the law's limitations, while D incorrectly states the behavior of resistors.
