NEET Physics Ohm's Law Assertion Reason Question
Assertion (A): The equivalent emf of two cells in parallel is the sum of their emfs divided by the sum of their internal resistances.
Reason (R): The equivalent resistance of two cells in parallel is given by the sum of their internal resistances divided by their product.
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.
Correct Answer
Detailed Explanation
The equivalent emf is not the sum of the emfs divided by the sum of the resistances. It is given by the formula (ε1r2 + ε2r1) / (r1 + r2).
