c) The circuit diagram for a Schering Bridge is shown in Figure Q4c is used to make measurements on a sample of insulation at 50 Hz. Both ends of the sample and the standard capacitor are connected to the high voltage side of the bridge. At balance conditions, the following readings were recorded; R3 = 10002 C2 = 500 pF, R4 = 2002, C4 = 223 nF. i) Calculate the tand of the sample dielectric. ii) Calculate the parallel equivalent...
