Question 3.11: In the circuit in Fig. 3.34, determine the currents i1, i2, ...
In the circuit in Fig. 3.34, determine the currents i_{1}, i_{2}, \text { and } i_{3}.
The schematic is shown in Fig. 3.35. (The schematic in Fig. 3.35 includes the output results, implying that it is the schematic displayed on the screen after the simulation.) Notice that the voltage-controlled voltage source E1 in Fig. 3.35 is connected so that its input is the voltage across the 4-Ω resistor; its gain is set equal to 3. In order to display the required currents, we insert pseudocomponent IPROBES in the appropriate branches. The schematic is saved as exam311.sch and simulated by selecting Analysis/Simulate. The results are displayed on IPROBES as shown in Fig.3.35 and saved in output file exam311.out. From the output file or the IPROBES, we obtain i_{1}=i_{2}=1.333 A \text { and } i_{3}=2.667 A.
