## Main Question or Discussion Point

Hi there,

I have a circuit in which consists of a resistance (rs) in series with parallel combination of capacitor and resistance(rc). I want to calculate value of rs. So i did this by calculating total impedance Ztotal which is V/I and then substracting impedance of parallel rc circuit.

Ztotal=rs+Zcrc where Zcrc is the impedance of the parallel rc.

I know the impedance for the parallel rc circuit but i want to get rid off the jth term which is present in the reactance term of the capacitor. How it can be done??

Xc=1/jwc

then here how to eliminate the jth term because i will subtract this impedance of parallel rc circuit from the total impedance to calculate rs.

thanks
