Physics-Ohm's Law
NEET Physics Ohm's Law MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements regarding Ohm's Law is correct?
A
Ohm's Law is valid for materials where the resistivity is independent of the electric field.
B
Ohm's Law applies universally to all conducting devices regardless of their properties.
C
A diode obeys Ohm's Law across all voltage values.
D
A resistor exhibits a non-linear I-V relationship at high electric fields.
Correct Answer
Option A
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.
