+//Problem 13.22: Find the value of the load resistor RL shown in Figure 13.51(a) that gives maximum power dissipation and determine the value of this power.

+

+//initializing the variables:

+V = 15; // in volts

+R1 = 3; // in ohms

+R2 = 12; // in ohms

+

+//calculation:

+//Resistance RL is removed from the circuit as shown in Figure 13.51(b).

+//The p.d. across AB is the same as the p.d. across the 12 ohm resistor.

+E = (R2/(R1 + R2))*V

+//Removing the source of e.m.f. gives the circuit of Figure 13.51(c),

+//from which resistance, r

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

+//The equivalent Th´evenin’s circuit supplying terminals AB is shown in Figure 13.51(d), from which, current I = E/(r + RL)

+//For maximum power, RL = r

+RL = r

+I = E/(r + RL)

+//Power, P, dissipated in load RL, P

+P = RL*I^2

+

+printf("\n (a) the value of the load resistor RL is %.1f ohm",RL)

+printf("\n (b) maximum power dissipation = %.0f W",P)
