The application of tensor algebra is found in the electric network, induction motors, and mathematical theories of communication etc., which many great peoples have sought out. We are shown electric networks have distributed-parameter circuits and lumped-parameter cirtuits roughly. Tensor algebra was applied lumped-parameter circuits, but some part of distributed-parameter circuits were not clear about properties of tensor algebra. So the author tried to apply tensor algebra with "tensor for circuits" of KRON to fundamental equations of distributed-parameter circuits. In this paper, he believes we will suggest some new problems about distributed-parameter circuits.
