Using the theory of electrical network, we first obtain simple formulas for the number of spanning trees of a complete bipartite graph containing a certain matching or a certain tree. Then we compute the effective resistances (ie, resistance distance in graphs) in the nearly complete bipartite graph G (m, n, p)= K m, n− p K 2 (p≤ min {m, n}), which extends a recent result (Ye and Yan, 2019) on the effective resistances in G (n, n, p). As a corollary, we obtain the Kirchhoff index of G (m, n, p) which extends a previous result by Shi and Chen. Using the effective resistances in G (m, n, p), we find a formula for the number of spanning trees of G (m, n, p). In the end, we prove a general result for the number of spanning trees of a complete bipartite graph containing several edges in a certain matching and avoiding others.
