NEET Physics Ohm's Law Assertion Reason Question
Assertion (A): A linear V-I curve implies that the resistance is constant for a conductor.
Reason (R): The resistivity of a material is independent of the magnitude and direction of the applied electric field.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
A linear V-I curve indicates that resistance is constant as per Ohm's Law. The resistivity being independent of the electric field supports this by ensuring the linear behavior of I-V characteristics.
