Unformatted text preview: V d = R d R c + R d V in (b) If V out = 0, then what must be true about V b and V a ? Show that V out = 0 if and only if R a R d = R b R c . (c) Suppose that R a R d = R b R c and a 3 . 5 resistor is connected across the V out terminals. Find the current through the 3 . 5 resistor. (d) Suppose V in = 24 V, R a = 3 , R b = 6 , R c = 2 , and R d = 2 . Find V out . 2 Figure 3: Wheatstone bridge circuit. 4 In the circuit of Figure 4, it is required that I 1 = 0 . 5 I in . Find the resistance R (in ), the equivalent conductance G eq , the current I 2 in terms of I in , and the voltage V in in terms of I in . Figure 4: Model circuit for Problem 4. 3...
