The short side is the negative end, with a lower electric potential, and the long side is the positive end, with a higher electric potential. ... WebSo the current is lower for a high resistor because it lets fewer charge through it per second, not because the electrons intuitively "know" which path has least resistance. Electrons will go through every path, but lower resistance means some paths will let electrons through at a higher rate and therefore have a higher current. fishing net for wading
