QJEEM22Ph3f48: JEE Main 2022 Physics - Class 12 JEEM22Ph3f48 Solution: Given below are two statements: one is labelled as Assertion A…
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.
Multiple Choice Options
- A Both A and R are true and R is the correct explanation of A.
- B Both A and R are true but R is NOT the correct explanation of A.
- C A is true but R is false.
- D A is false but R is true.
Step-by-Step Verified Solution
Since they have low temperature coefficient of resistance, their resistance remains almost constant.
