+//Problem 40.12: Determine the energy stored in a 10 nF capacitor when charged to 1 kV, and the average power developed if this energy is dissipated in 10 μs.
+
+//initializing the variables:
+e0 = 8.85E-12; 
+er = 1;
+C = 10E-9; // in Farad
+V = 1000; // in Volts
+t = 10E-6; // in sec
+
+//calculation:
+//energy stored,Wf
+Wf = C*V*V/2
+//average power developed
+Pav = Wf/t
+
+printf("\n\n Result \n\n")
+printf("\n the energy stored is %.2E J",Wf)
+printf("\nthe average power developed is %.0f W",Pav)
