To determine Calculate the current i o in the given circuit in PSPICE using node-voltage method. Explanation The given circuit is redrawn with reference node and the node voltages v 1 and v 2 as shown in Figure 1. Apply Kirchhoff’s current law at node v 1 in Figure 1. v 1 − 20 2 k + v 1 30 k + v 1 − v 2 5 k = 0 v 1 2 k − 20 2 k + v 1 30 k + v 1 5 k − v 2 5 k = 0 v 1 ( 1 2 × 10 3 + 1 30 × 10 3 + 1 5 × 10 3 ) − v 2 5 × 10 3 = 20 2 × 10 3 { ∵ 1 k = 10 3 } 7.3333 × 10 − 4 v 1 − 2 × 10 − 4 v 2 = 0.01 (1) Apply Kirchhoff’s current law at node v 2 in Figure 1. v 2 − 20 5 k + v 2 1 k + v 2 − v 1 5 k = 0 v 2 5 k − 20 5 k + v 2 1 k + v 2 5 k − v 1 5 k = 0 − v 1 5 × 10 3 + v 2 ( 1 5 × 10 3 + 1 1 × 10 3 + 1 5 × 10 3 ) = 20 5 × 10 3 { ∵ 1 k = 10 3 } − 2 × 10 − 4 v 1 + 1.4 × 10 − 3 v 2 = 4 × 10 − 3 (2) Rearrange the equation (2) as follows, 2 × 10 − 4 v 1 = 1.4 × 10 − 3 v 2 − 4 × 10 − 3 v 1 = 1
