PROBLEMS

P2.1: Figure P2.1 shows an electrical circuit with resistors and voltage sources. Write a MATLAB program
to determine the current in each resistor, using the mesh current method based on Kirchhoff’s second voltage
law. Given V 1 = 37 V, V 2 = 19 V, V 3 = 25 V, R 1 = 16 Ω, R 2 = 19 Ω, R 3 = 11 Ω, R 4 = 10 Ω, R 5 = 6 Ω, R 6 = 15 Ω,
R 7 = 9 Ω, R 8 = 14 Ω, R 9 = 6 Ω and R 10 = 3 Ω.

P2.2: Write a MATLAB program in a script file that computes the current through each resistor and the
power dissipated in each in a circuit that has resistors connected in parallel as shown in Fig. P2.2. Use the
script file for the circuit shown in Fig. P2.2.
Note that when several resistors are connected in a circuit in parallel, the current through each of them is given
