In this paper, using the intimate relations between random walks and electrical networks, we first prove the following effective resistance local sum rules: c"i@W"i"j+@?k@?@C(i)c"i"k(@W"i"k-@W"j"k)=2, where @W"i"j is the effective resistance between vertices i and j, c"i"k is the conductance of the edge, @C(i) is the neighbor set of i, and c"i=@?"k"@?"@C"("i")c"i"k. Then we show that from the above rules we can deduce many other local sum rules, including the well-known Foster's k-th formula. Finally, using the above local sum rules, for several kinds of electrical networks, we give the explicit expressions for the effective resistance between two arbitrary vertices.
