ABSTRACT=<p>A novel relation between the Moore-Penrose inverses of two nullity-1 <italic>n</italic> × <italic>n</italic> Hermitian matrices which share a common null eigenvector is established, and its application in electrical networks is illustrated by applying the result to Laplacian matrices of graphs.</p>
