Kirchhoff ’s junction rule is a reflection of
A. conservation of current density vector.
B. conservation of charge.
C. the fact that the momentum with which a charged particle approaches a junction is unchanged (as a vector) as the charged particle leaves the junction.
D. the fact that there is no accumulation of charges at a junction.
The correct answers are the options (b,d)
Explanation: According to the law of conservation of charges, the charge of a system will stay constant. From this, it can be derived that net charge flowing into a junction is equal to the net charge going out of the system.
