Definition: one-dimensionally distributed two-terminal-pair circuit element characterized by lineic inductance l, lineic capacitance c, lineic resistance r and lineic conductance g which may all be functions of the same space coordinate x, where the voltage u(x, t) and the electric current i(x, t), where t is the time, are related by the partial differential equations:
