you mean something like this? http://www.crlsresearchguide.org/00_Introduction.asp (if yes than glad i could help, if no then sorry)
Parallel circuits allow one each of it s leg to receive the same voltage regardless of resistance, as opposed to a series circuit that is forced to split up it s voltage to each load. To get the same results as a parallel circuit, a series circuit would have to have to have the parallel circuits voltage times each load it is supposed to power. Instead of a 12V, 5 leg parallel circuit, it would have to be a 60V series circuit. It s much easier to make a 12V batter than a 60V battery.
