NEET Physics Resistivity and Conductivity Assertion Reason Question
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Alloys such as constantan and manganin are used in making standard resistance coils. Reason R: Constantan and manganin have very small value of temperature coefficient of resistance. In the light of the above statements, choose the correct answer from the options given below.
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 true but R is false.
Correct Answer
Detailed Explanation
Both statements are true, and the reason correctly explains why these alloys are used for resistance coils.
