Unformatted text preview: headed arrow emphasizes tiai a source transformation is bilateral that is, lve can startwith either configuration and dedve the other. We need to find the relationship bctwcorl o, and ir thal guamntees the two configurations in Fig. 4.36 are equivalent with respect 1() iodes a,b. Equivalence is achieved if an_v resistor R, experiences the same current flo\l:, and thus the same voltage drop, whether connected between nodes a,b in Fig.4.36(a) or Fig.4.36(b). Suppose R, is connecled betlveen nodes a,b in Fig. 4.36(a). Using Ohm\ law. thc current in n, is 14.52) Now suppose thc same resistor R, is connected between nodes a,b in Fig.4.36(b). Using current division, lhe cunent in R, is If the lrvo circuits in Fig. 4.36 are equivalent. these resistor currents must be the same. Equating ihe righlhand sides ofEqs.4.52 and:1.53 and sirnplitying, , ' = R 2 A 2 5 V 14.54)...
