NEET Chemistry Batteries Assertion Reason Question
Assertion (A): In a practical battery, the voltage should not vary appreciably during its use.
Reason (R): A practical battery must be compact and light to be of practical use.
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
While both the assertion and reason are true, the reason does not explain why the voltage should not vary during the use of a battery. The voltage consistency is related to the efficient conversion of chemical energy to electrical energy.
