An ac voltage $V_i = 12 \sin $100 \pi t$ \text{ V}$ is applied between points A and B in a network of two ideal diodes and three resistors as shown in figure. During the positive half-cycle of the input voltage $V_i$ supplied to the network. (a) Identify which of the two diodes will conduct and why ? (b) Redraw an equivalent circuit diagram to show the flow of current. (c) Calculate the output voltage drops $V_0$ across the three resistors when the input voltage attains its peak value.
