+//Problem 35.07: Determine the optimum value of load resistance for maximum power transfer if the load is connected to an amplifier of output resistance 448 ohm through a transformer with a turns ratio of 8:1.
+
+//initializing the variables:
+Ro = 448; // in ohm
+tr = 8; // turn ratio N1/N2
+
+//calculation:
+//The equivalent input resistance r of the transformer must be Ro for maximum power transfer.
+r = Ro
+RL = r*(1/tr)^2
