Kirchhoff''s junction rule is a reflection of

Answer»

CONSERVATION of current density vector.
conservation of charge.
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
the fact that there is no accumulation of CHARGES at a junction

Solution :(B,D) Kirchhoff.s junction law : Algebraic sum of current meeting junction of a ELECTRICAL circuit is zero. Thus, charge is conserved.
At any junction whatever quantity of charge enter in given time similar charge leaves similar time. Means, charge is not COLLECTED at junction.
