As we learned

Impedence -

Z= \sqrt{R^{2}+\left ( X_{L}-X_{c} \right )^{2}}

-

 

 Indepence of circuit, Z= \sqrt{{R}^{2}+(X_{L}-X_{C})^{2}}

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

Z= \sqrt{R^{2}+\left ( 2\pi f L-\frac{1}{2\pi \int C} \right )^{2}}

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

Z= 62.03\Omega
