   To set up a current source why do we need to place the resistances in parallel rather than than placing them in series.

   well I think thats because the current divides in the parallel circuit.
   
   It would be same throughout in the series circuit, so there might be no use for a sonnection in the series. And it also depends on the amount of current needed through the circuit.
   
   I think

   Welcome to the PF. Are you asking about Norton and Thevinin Equivalent circuits?

   Ok, then did the link answer your question? And what do you mean by "set up" a current source? Do you mean in a simulation?
