Physics-Kirchhoff's Laws
NEET Physics Kirchhoff's Laws Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Kirchhoff's junction rule states that the sum of currents entering a junction equals the sum of currents leaving it. | Reason (R): In a parallel combination of cells, the equivalent emf is the sum of the individual emfs of the cells.
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.
Correct Answer
Option C
Detailed Explanation
The assertion is true as Kirchhoff's junction rule is about conservation of current at a junction. The reason is false because in parallel combinations, the equivalent emf is not simply the sum of individual emfs.
