a Phasor diagram of a dielectric material. Ir is the current due to losses on the insulator and Ic represents the capacitive current. b Phasor diagram of the current components of both branches. c Circuit implemented for current measurement. Rx and Cx are unknown parameters, while Cs = 99.7 pF, R1 = 265.25 Ω and R2 = 25 Ω
