Question:
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 the charged particle leaves the junction
(d) the fact that there is no accumulation of charges at a junction
Solution:
The correct answer is
(b) conservation of charge
(d) the fact that there is no accumulation of charges at a junction
