Since the +v R, + v R, + v R, = 5 + 15 + 30 = 50 Now suppose that V R , and V R, are known to be 18 V and 12 V, respectively. Then V R , = 20 V. 8 Consider the network in Fig. 10. a + VR I - b + VR C + Rz R1 + ' SOLUTION Note that this network has three closed paths: the left loop, right loop, and outer loop. Applying our policy for writing KVL equations and traversing the left loop starting at point a, we obtain V R, + V R4 - 16 - 24 = 0 VR d 3 R3 24 V The corresponding equation for the right loop starting at point b is V R, + V R3 + 8 + 16 - V R4 = 0 + SY The equation for the outer loop starting at point a is 16 V V R , + V R, + V R, + 8 - 24 = 0 Note that if we add the first two equations, we obtain the third equation.

19a. 13 Given the circuit in Fig. 20a, let us find I, V bd, and the power absorbed by the 30-kD resistor. 20 Circuit used in Example 2. 13. 1 mA, but its direction is opposite to that assumed. The voltage V bd can be calculated using either of the closed paths abdea or bcdb. l mA in either equation yields V bd = 10 V. 3mW Now from the standpoint of determining the voltage V be, we can simply add the sources since they are in series, add the remaining resistors since they are in series, and reduce the network to that shown in Fig.

30d. 1 =-mA 8 The following example is, in essence, the reverse of the previous example in that we are given the current in some branch in the network and are asked to find the value of the input source. 21 Given the circuit in Fig. 1 = 12 + ls = 3mA Now KVL applied to any closed path containing V O will yield the value of this input source. 31 -V0 + 6kI 1 + 3kl5 + lk/5 + 4k/ 1 = 0 Example circuit for analysis. 5 mA, SOLUTION If 14 = 1mA, then from Ohm's law, Vb= 3 V. Vb can now be used to calculate/ 3 = 1 mA.
