+// Given data
+I_m = 1*(10^-3); //Full scale deflection of the movement in ampere
+R_m = 100; //Internal resistance of the movement(the coil) in ohm
+I = 100*(10^-3); //Full scale of the ammeter including the shunt in Ampere

+//Calculations
+I_s = I - I_m; // calculating current through shunt
+R_s = I_m * R_m/ I_s; //calculating shunt to be added
+printf("The value of the shunt resistance required, R_s = %0.2f ohm",R_s);
+
+//Result
+// The value of the shunt resistance required, R_s = 1.01 ohm
