In one-dimensional conductors, interactions result in correlated electronic systems. At low energy, a hallmark signature of the so-called Tomonaga-Luttinger liquids (TLL) is universal conductance curve predicted presence an impurity. A seemingly different topic quantum laws electricity, when distinct conductors are assembled circuit. particular, conductances suppressed at phenomenon called dynamical Coulomb blockade (DCB). Here we investigate mesoscopic circuits constituted by short single-channel conductor series with resistance, and demonstrate proposed link to TLL physics. We reformulate establish experimentally recently derived phenomenological expression for using wide range circuits, including carbon nanotube data obtained elsewhere. By confronting both curve, mapping between DCB transport across
