| Abstract: | Using the electric approach, we derive a formula that expresses an expected hitting time of a random walk between two vertices a and b of a graph G as a convex linear combination of expected hitting times of walks between a and b on subgraphs of G, provided certain condition on a and b is satisfied. Then we use this formula in several applications. |
