A) \[57.32\,\Omega \]
B) \[79.48\,\Omega \]
C) \[89.5\,\Omega \]
D) \[99.1\,\Omega \]
Correct Answer: D
Solution :
Total impedence of L-C-R circuit \[Z=\sqrt{{{R}^{2}}+{{({{X}_{L}}-{{X}_{C}})}^{2}}}\] \[{{X}_{L}}=\omega L=2\pi \,fL\] \[{{X}_{L}}=\frac{1}{2\pi \,fC}\] \[f=50\] Substituting the values \[Z=99.1\Omega \]You need to login to perform this action.
