Determine the value of v and the power supplied by the independent current source in Fig. 3.17. 6 kn 2ix V 24 mA ww 2 ΚΩ I FIGURE 3.17 A voltage v and a current i6 are assigned in a single-node-pair circuit containing a dependent source. By KCL, the sum of the currents leaving the upper node must be zero, so that i6-2ix -0.024 - ix = 0 Again, note that the value of the dependent source (2i,) is treated the same as any other current would be, even though its exact value is not known until the circuit has been analyzed. We next apply Ohm's law to each resistor: Therefore, ν -v i6 = and ix = 6000 2000 v 6000 - -V v 2 -0.024- = 0 2000 2000 and so v = (600) (0.024) = 14.4 V. Any other information we may want to find for this circuit is now eas- ily obtained, usually in a single step. For example, the power supplied by the independent source is p24 = 14.4(0.024) = 0.3456 W (345.6 mW).
