The question as text
Fig. 8.1 shows a circuit that produces rectification of an alternating input voltage. VIN VOUT R Fig. 8.1 The input voltage VIN is sinusoidal. The rectified output voltage VOUT is applied across resistor R. The variation of VIN with time t has amplitude V0 and period T, as shown in Fig. 8.2. 0 0 V0 VIN –V0 T t 2T Fig. 8.2 The root-mean-square (r.m.s.) value of VIN is 6.0 V.
