 Circuits having the form of one shown in Figure 3.55 are termed bridge circuits. iin R R + Vout Figure 3.55 

Circuits having the form of one shown in Figure 3.55 are termed bridge circuits. iin R R + Vout Figure 3.55 R3 R (a) What resistance does the current source see when nothing is connected to the output terminals? (b) What resistor values, if any, will result in a zero voltage for tout? 452. Find the current i when the current source fin (c) Assume R = 19, R = 20, R3 = 20 and Ra is Im [(4+25) e/220]. Express your answer as a sinusoid.
