NEET Chemistry Conductance Assertion Reason Question
Assertion (A): The electrical resistance of an object depends on its length and cross-sectional area.
Reason (R): Resistivity is a measure of how strongly a material opposes the flow of electric current.
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 assertion and reason are both true, and the reason correctly explains the assertion. The resistance is directly proportional to the length and inversely proportional to the cross-sectional area, while resistivity is the material-specific factor influencing resistance.
