+//Problem 20.24: An a.c. source of 24 V and internal resistance 15 kohm is matched to a load by a 25:1 ideal transformer. Determine (a) the value of the load resistance and (b) the power dissipated in the load.
+
+//initializing the variables:
+tr = 25; // teurn ratio
+V = 24; // in Volts
+R1 = 15000; // in Ohms
+Rin = 15000; // in ohms
+
+//calculation:
+//Turns ratio, tr = N1/N2 = V1/V2
+//For maximum power transfer R1 needs to be equal to 15 kohm
+RL = R1/(tr^2)
+//The total input resistance when the source is connected to the matching transformer is
+Rt = Rin + R1
+//Primary current,
+I1 = V/Rt
+//N1/N2 = I2/I1
+I2 = I1*tr
+//Power dissipated in load resistor RL
+P = I2*I2*RL
+
+printf("\n\n Result \n\n")
+printf("\n (a) the load resistance is %.0f ohm", RL)
+printf("\n (b)  power dissipated in the load resistor is %.2E W", P)
