+V=200;//voltage in volts

+f=50;//frequency in hz

+R1=10;//resistance in ohms

+L1=0.0023;//inductance in henry

+R2=5;//resistance in ohms

+L2=0.035;//inductance in henry

+//CALCULATIONS

+Xl1=(2*%pi*f*L1);//inductive reactance in branch 1 in ohm

+Xl2=(2*%pi*f*L2);//inductive reactance in branch 2 in ohm

+Y=Y1+Y2;//total admittance in mho

+I1=V*(Y1);//current through branch1

+I2=V*(Y2);//current through branch2

+I=I1+I2;//total current in A

+theta=atan(imag(I)/real(I));//angle in radians

+pf_of_combination=cos(theta);//powerfactor---->lagging
