As we learned

 

Impedence -

Z= \sqrt{X_{C}^{2}+R^{2}}=\sqrt{R^{2}+\left ( \frac{1}{\omega c} \right )^{2} }

-

 

   Impedence, Z=\sqrt{R^{2}+X_{C}^{2}}

                            =\sqrt{R^{2}+\left ( \frac{1}{wc} \right )^{2}}

                            =\sqrt{R^{2}+\left ( \frac{1}{2\pi\int c } \right )^{2}}

                            =\sqrt{(0.2\times 10^{3})^{2}+\left ( \frac{1}{2\times \pi \times 50\times 4\times 15^{3}} \right )^{2}}

                            Z=200.0015847\Omega

                            Z=0.2K\Omega
