A) \[{{10}^{5}}\Omega \]
B) \[{{10}^{4}}\Omega \]
C) \[{{10}^{6}}\Omega \]
D) \[{{10}^{10}}\Omega \]
Correct Answer: A
Solution :
(a) \[{{10}^{5}}\Omega \] Here, \[R=20\,\Omega ,\,C=0.1\,\mu F\] \[=0.1\times {{10}^{-6}}F={{10}^{-7}}F\] Impedance, \[Z=\sqrt{{{R}^{2}}+\frac{1}{{{\omega }^{2}}{{C}^{2}}}}=\sqrt{{{20}^{2}}+\frac{1}{{{(100)}^{2}}\times {{({{10}^{-7}})}^{2}}}}\] \[=\sqrt{400+{{10}^{10}}}={{10}^{5}}\Omega \]
