Kirchoff's junction rule is a reflection of

Options

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.

Answer

B, D

Explanation

Kirchhoff's junction rule is also known as kirchhoff's current law wchich states that the algebraic sum of the currents flowing towards any point in an electric network is zero. i.e., charges are conserved in an electric network. So, kirchhoff's junction rule is the reflection of conservation of charge.
