Chapter Problem 18P Step solution Step Refer to Figure the textbook Apply voltage source across terminals and ground as shown Figure 1. X R, kΩ R. 1 2 Figure Step Apply Kirchhoff's current node 1. Apply Kirchhoff's current at node 2 Substitute for equation (1) Substitute for equation (2) Step Apply Kirchhoff's current law (4) Substitute for 2 1x Calculate the equivalent resistance Therefore the equivalent Step Calculation equivalent if the raised to 1.2 Apply voltage source Vx across terminals and ground shown Figure X kΩ R. 2 Figure Step Apply Kirchhoff's current law at node 1 1kQ (5) Apply Kirchhoff's current (6) Substitute for equation (6) (7) Substitute for equation (5) 1.957 From equation (7) Step Apply current (8) Substitute for V1 and for 0.96V 0.96 Calculate equivalent resistance V. Therefore the equivalent resistance
