D’Arsonval meter, as shown in Figure Q3(a) is used to measure the AC voltage with amplitude +20 V. Usually, this meter measures the DC voltage only. To measure the AC voltage, some circuit modifications need to be done. Therefore, you are required to design a modification circuit for the D’Arsonval meter. Assume the internal resistance of the meter, Rm = 2002 and current full-scale deflection, Ifsd = 300 µA.
