+//Problem 13.21: A d.c. source has an open-circuit voltage of 30 V and an internal resistance of 1.5 ohm. State the value of load resistance that gives maximum power dissipation and determine the value of this power.
+
+//initializing the variables:
+V = 30; // in volts
+r = 1.5; // in ohms
+
+//calculation:
+//current I = E/(r + RL)
+//For maximum power, RL = r
+RL = r
+I = V/(r + RL)
+//Power, P, dissipated in load RL, P
+P = RL*I^2
