Current source

[fusion911]

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?

yes
the very same

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?
