This applies equally well if instead of a junction of
several lines, we consider a point in a line The proof of this rule follows from the fact that
when currents are steady, there is no accumulation
of charges at any junction or at any point in a line Thus, the total current flowing in, (which is the rate
at which charge flows into the junction), must equal
the total current flowing out
