Loop/Mesh Analysis

Use loop/mesh analysis to determine the loop currents and also the voltages across the resistors of the circuit as shown in Fig.3.1 (see attached file). Use Matlab to calculate these values. After finding the loop currents using Matlab, calculate the voltages across the resisters by multiplying the loop currents with corresponding resistor values. Enter these values under the 'Calculated' column in Table 1 (see attached file). Please include the matlab code as well. Thanks.

Node Analysis

Use nodal analysis to determine the node voltages and also the branch currents of the circuit as shown in Fig.3.2. Use Matlab to calculate these values. Enter these readings in Table 2 under the 'calculated' column. (Note: Node voltage VA is known, that is, 10 V. So you need to write nodal equations at B and C only for the circuit analysis). Please type it in Microsoft Word because it is clearer for me to see and understand. Also, please include the Matlab code too. Thanks

Node Voltage Analysis

Using node voltage analysis in the circuit of Figure P3.6 (see attached file), find the three indicated node voltages. Let I = 0.4 A; R1 = 4000 ohms; R2 = 150 ohms; R3 = 50 ohms; R4= 100 ohms; R5 = 200 ohms; V = 20 volts.

KCL problem

Using KCL, perform a node analysis on the circuit shown in Figure P3.13 (see attached file), and determine the voltage across R4. Note that one source is a controlled source! Let V_s = 10 volts; A_v = 70; R1 = 4.4 kΩ; R2 = 3.6 kΩ; R3 = 13.6 kΩ; R4 = 440 Ω.

Mesh Current Analysis

Use mesh current analysis to find the current i in the circuit of Figure P3.16 (attached file). Let V = 2.8 V; R1 = 25 Ω; R2 = 0.6 kΩ; R3 = 165 Ω; g_m = 0.2 S; R4 = 220 Ω.
