In a RC network first find Xc = 1/2 pi fc.

Xc = 1/2*3.14*3000*0.22*10^-6.

= 1/18840*.22*10^-6.

Xc = 241.26.


Z=sqrt (r^2 + Xc^2).
=sqrt (200^2 + 241.26^2).
=sqrt (40000 + 58148.49).
= sqrt (98148.49).

Z = 313.28.

Xc=(1/2*pi*f*c)
=(1/2*3.14*3K*.22u)=241.14

Z=sqrt(R^2+Xc^2)
=sqrt(200^2 + 241.14)
=313.14 ohm.
