+//Problem 32.03: Use the superposition theorem to obtain the current flowing in the (4 + i3) ohm impedance of Figure 32.16.
+
+//initializing the variables:
+rv1 = 30; // in volts
+rv2 = 30; // in volts
+thetav1 = 45; // in degrees
+thetav2 = -45; // in degrees
+R1 = 4; // in ohm
+R2 = 4; // in ohm
+R3 = %i*3; // in ohm
+R4 = -1*%i*10; // in ohm
+
+//calculation:
+//voltage
+V1 = rv1*cos(thetav1*%pi/180) + %i*rv1*sin(thetav1*%pi/180)
+V2 = rv2*cos(thetav2*%pi/180) + %i*rv2*sin(thetav2*%pi/180)
+//The network is redrawn with V2 removed, as shown in Figure 32.17.
+//Current I1 and I2 are shown in Figure 32.17. From Figure 32.17,
+Re1 = R4*(R2 + R3)/(R4 + R3 + R2)
+Re2 = Re1 + R1
+//current
+I1 = V1/Re2
+I2 = (R4/(R2 + R3 + R4))*I1
+//The original network is redrawn with V1 removed, as shown in Figure 32.18
+//Currents I3 and I4 are shown in Figure 32.18. From Figure 32.18,
+Re3 = R1*(R2 + R3)/(R1 + R3 + R2)
+Re4 = Re3 + R4
+I3 = V2/Re4
+I4 = (R1/(R2 + R3 + R1))*I3
+//If the network of Figure 32.18 is superimposed on the network of Figure 32.17, it can be seen that the current in the (4+i3) ohm impedance is given by
+Ir4i3 = I2 - I4
