Question: exercise 1218 the circuit in figure 16 is the same...

Question details

Exercise 1.2.18 The circuit in Figure 1.6 is the same as for the previous problem, but now let us focus on the loop currents 0.1Ω 0.212 0.1Ω 0.2 S2 C2 0.5 S2 0.5 Ω 0.1Ω L3 0.5 Ω T3 T4 9 V 0.2 Ω 0.1Ω 0.2 S2 n2 Figure 1.6 Electrical circuit with loop currents (a) Write down a linear system Ax - b of four equations for the four unknown loop currents. (b) Solve the system for r. Calculate the residual r = b-Ax, where x denotes vour computed solution. (c) Using Ohms law and the loop currents that you just calculated, find the voltage drops from the node labeled ni to the nodes labeled n2 and n3. Are these in agreement with your solution to Exercise 1.2.17? Using Ohms law and the voltages calculated in Exercise 1.2.17, find the current through the resistor labeled R1. Is this in agreement with your loop current calculation? (d)
