A) \[\sqrt{{{R}^{2}}+\frac{1}{{{\omega }^{2}}{{L}^{2}}}}R\]
B) \[{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}\]
C) \[\sqrt{{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}}\]
D) \[\sqrt{{{\omega }^{2}}{{L}^{2}}+\frac{1}{{{R}^{2}}}}\,\]
Correct Answer: C
Solution :
\[Z=\sqrt{{{R}^{2}}+X_{L}^{2}}=\sqrt{{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}}\]
