WebMoreover, we introduce the Laplacian matrix for directed graphs and express the effective resistance in terms of the pseudoinverse of Laplacian matrix. Since the notion of electrical networks is inherently related to undirected graphs, we deﬁne the resistance distance for directed graphs based on random walks. A.
