+// to calculate the equivalent parallel capacitance and resistance

+// example 8-5 in page 204

+clc;

+//Given dATA

+R3=10e+3;// resistance R3 in ohm

+f=100;//frequency in hertz

+Cs=0.068e-6; Rs=183.8; // series capacitance in farad and resistance in ohm

+//Calculation

+Xs=1/(2*%pi*f*Cs);// series capacitive reactance in ohm

+Rp=(Rs*Rs+Xs*Xs)/Rs;//equivalent parallel resistance in ohm

+Xp=(Rs*Rs+Xs*Xs)/Xs;//equivalent parallel capacitive reactance in ohm

+Cp=1/(2*%pi*f*Xp);// equivalent capacitance in farad

+R4=C1*R3/Cp;// parallel resistance in ohm

+R1=R3*Rp/R4;// parallel resistance in ohm

+printf("Rp=%.2f M-ohm\nCp=%.3f Micro-F\nR1=%.2f M-ohm\nR4=%.1f K-ohm",Rp/10^6,Cp*10^6,R1/10^6,R4/1000);

+//result

+//Rp=2.98 M-ohm

+//Cp=0.068 Micro-F

+//R1=2.03 M-ohm

+//R4=14.7 K-ohm
