+//Problem 40.10: A single-phase circuit is composed of two parallel conductors, each of radius 4 mm, spaced 1.2 m apart in air. The p.d. between the conductors at a frequency of 50 Hz is 15 kV. Determine, for a 1 km length of line, (a) the capacitance of the conductors, (b) the value of charge carried by each conductor, and (c) the charging current.
+
+//initializing the variables:
+e0 = 8.85E-12; 
+er = 1;
+D = 1.2; // in m
+r = 0.004; // in m
+f = 50; // in Hz
+V = 15000; // in Volts
+l = 1000; // in m
+
+//calculation:
+//capacitance
+C = %pi*e0*er/(log(D/r))
+//capacitance of a 1 km length
+Cpkm = C*l
+//Charge Q
+Q = Cpkm*V
+//Charging current
+I = V*2*%pi*f*Cpkm
+
+printf("\n\n Result \n\n")
+printf("\n capacitance per 1km length is %.2E F",Cpkm)
+printf("\n Charge Q is %.2E C",Q)
+printf("\n Charging current is %.3f A",I)
