+//Problem 13.07: Use Th´evenin’s theorem to find the current flowing in the 10 ohm resistor for the circuit shown in Figure 13.28(a).

+

+//initializing the variables:

+V = 10; // in volts

+R1 = 2; // in ohms

+R2 = 8; // in ohms

+R3 = 5; // in ohms

+R = 10; // in ohms

+

+//calculation:

+//The 10 ohm resistance branch is short-circuited as shown in Figure 13.28(b).

+//Current I1

+I1 = V/(R1 + R2)

+//p.d. across AB, E

+E = R2*I1

+//the resistance ‘looking-in’ at a break made between A and B is given by

+r = R3 + (R1*R2)/(R2 + R1)

+//The equivalent Th´evenin’s circuit is shown in Figure 13.28(d), the current in the 10 ohm resistance is given by:

+I = E/(r + R)

+

+printf("\n\n Result \n\n") 

+printf("\n the current in the 10 ohm resistance is given by %.3f A",I)
