Effective resistance random walks

WebThe probability that a random walk will return to the origin before hitting Fn will then be given by 1 deg O X x˘O gn(x) (5) By Ohm’s law this is equal to 1 (deg O)(resistance between O and Fn) (6) So if the resistance between O and Fn is finite, the random walk is transient, but if it is infinite, the random walk is recurrent.
