Figure Pl.6(a) shows a two-resistor voltage divider. Its function is to generate a voltage Vo (smaller than the power-supply voltage Voo) at its output node X The circuit looking back at node X is equivalent to that shown in Fig. Pl.6(b) Observe that this is the Thvenin equivalent of the voltage- divider circuit. Find expressions for Vo and Ro VDO X Ro (a) Figure Pl.6 (a) Ro www (b) Figure P1.6 (b) 27
