| Assertion (A): Kirchhoff's junction rule is applicable for any number of lines meeting at a point in an electrical circuit. |
| Reason (R): When there is a flow of steady current, then there is no accumulation of charge at the junction. |
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 and R is true
Correct Answer: A
Solution :
| Option [a] is correct |
| Explanation: Kirchhoff's junction rule is applicable at any point of an electrical circuit and there is no limitation of number of lines meeting at that point. So the assertion is true. |
| While steady current is flowing there is no accumulation of charge at the junction. Total incoming charge = total outgoing charge. |
| So the reason is also true and explains the assertion. |
