At issue was that unlike water an electrical current doesn’t seek the easiest or shortest route from one point to another; to electricity all pathways are equal. So if one provides two paths, it will take them both simultaneously and indiscriminately, even if the second is twenty times longer than the first; if one provides forty paths, this pattern of all-options-at-once travel is the same. The simplest explanation of the difference between the two kinds of circuits is that parallel circuits allow for this sort of both/and flow pattern, whereas series circuits give electricity only a single
