(a) To determine Calculate the total power developed in the given circuit using node-voltage method in PSPICE. 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 1 k + v 1 − v 2 1250 = − 20 m v 1 1 × 10 3 + v 1 1250 − v 2 1250 = − 20 × 10 − 3 { ∵ 1 m = 10 − 3 , 1 k = 10 3 } ( 1 × 10 − 3 + 8 × 10 − 4 ) v 1 − 8 × 10 − 4 v 2 = − 20 × 10 − 3 1.8 × 10 − 3 v 1 − 8 × 10 − 4 v 2 = − 20 × 10 − 3 (1) Apply Kirchhoff’s current law at node v 2 in Figure 1. v 2 4 k + v 2 2 k + v 2 − v 1 1250 + v 2 − 2500 i Δ 200 = 0 v 2 4 × 10 3 + v 2 2 × 10 3 + v 2 1250 − v 1 1250 + v 2 200 − 2500 i Δ 200 = 0 { ∵ 1 k = 10 3 } − v 1 1250 + ( 1 4 × 10 3 + 1 2 × 10 3 + 1 1250 + 1 200 ) v 2 − 2500 i Δ 200 = 0 − 8 × 10 − 4 v 1 + 6.55 × 10 − 3 v 2 − 12.5 i Δ = 0 (2) In Figure 1, the current i Δ is calculated by using Ohm’s law as follows. i Δ = v 2 − v 1 1250 (3) Substitute equation (3) in equation (2). − 8 × 10 − 4 v 1 + 6.55 × 10 − 3 v 2 − 12.5 ( v 2 − v 1 1250 ) = 0 − 8 × 10 − 4 v 1 + 6.55 × 10 − 3 v 2 − 0.01 v 2 + 0.01 v 1 = 0 9.2 × 10 − 3 v 1 − 3.45 × 10 − 3 v 2 = 0 Rearrange the equation as follows, 9.2 × 10 − 3 v 1 = 3.45 × 10 − 3 v 2 v 1 = 3.45 × 10 − 3 9.2 × 10 − 3 v 2 v 1 = 0.375 v 2 (4) Substitute equation (4) in equation (1). 1.8 × 10 − 3 ( 0.375 v 2 ) − 8 × 10 − 4 v 2 = − 20 × 10 − 3 6 (b) To determine Calculate the total power absorbed in the circuit using PSPICE.

How do we know that D1 is forward bias and D2 is reverse biased?

Solve it in a different way than the previous solution that I searched for

A lossless uncharged transmission line of length L = 0.45 cm has a characteristic impedance of 60 ohms. It is driven by an ideal voltage generator producing a pulse of amplitude 10V and width 2 nS. If the transmission line is connected to a load of 200 ohms, sketch the voltage at the load as a function of time for the interval 0 < t < 20 nS. You may assume that the propagation velocity of the transmission is c/2. Answered now answer number 2. Repeat Q.1 but now assume the width of the pulse produced by the generator is 4 nS. Sketch the voltage at the load as a function of time for 0 < t < 20 nS.
