Circuit diagram of an average reading ac voltmeter using semi-conductor diode is shown in figure. The diode conducts during the positive half cycle and does not conduct during the -ve half cycle, as shown in figure. The average current through the meter will be given by the expression Iav = Vav / 2R = 0.45 * [Vrms/R]
