| This sort of problem lies in mathematical method in physics. Grab a book of this topic from library, you can find the answer for sure.

hi,
the mathematical expressions are no different frm the principles that are used in analysing a BJT or FET. only thing is u need to know which transistor is sourcing or sinking.. which again can be done by calculating the bias point voltages from the circuit thereby calculating if the transistor is in active or saturation region.. since it being digital its more simple to fid in cut off or saturation... then for sinking the current is allowed to sink.. finsing a path to ground.. or allowed to source.. similar to fan in.. provides current for driving... from these and basic analysis.. u should be able to calculate the various voltages, i beleive.. and i think i have not misunderstood ur question..

divergent of field is postive means then it will indicate that corresponding field as source.
if it is negative than it will be called as sinking field.
hope u understand abt the concept.
for understanding this we have to familair with divergent operations in field theory.
Added after 2 minutes:
negative divergence is also called as convergence field(sink)
