+//Problem 21.11: A short-shunt compound generator supplies 80 A at 200 V. If the field resistance, Rf = 40 ohm, the series resistance, Rse = 0.02ohms  and the armature resistance, Ra = 0.04 ohm, determin  the e.m.f. generated.
+
+//initializing the variables:
+Is = 80; // in amperes
+Vs = 200; // in Volts
+Rf = 40; // in ohms
+Rse = 0.02; // in ohms
+Ra = 0.04; // in ohms
+
+//calculation:
+//Volt drop in series winding
+Vse = Is*Rse
+//P.d. across the field winding = p.d. across armature
+V1 = Vs + Vse
+//Field current, If
+If = V1/Rf
+//Armature current
+Ia = If + Is
+//Generated e.m.f. E
+E = V1 + Ia*Ra
