NEET Physics Ohm's Law Assertion Reason Question
Assertion (A): The resistance of a conductor is directly proportional to its length. | Reason (R): Doubling the length of a conductor doubles its resistance.
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
The NCERT context explains that resistance is proportional to length and shows that doubling the length doubles the resistance, making R the correct explanation of A.
