A) \[25\,\Omega \]
B) \[\sqrt{7}\,\Omega \]
C) \[5\,\Omega \]
D) \[19\,\Omega \]
Correct Answer: C
Solution :
In a series \[LCR\,\,AC\] circuit total impedence \[Z=\sqrt{{{R}^{2}}+{{({{X}_{L}}-{{X}_{C}})}^{2}}}\] \[Z=\sqrt{{{(3)}^{2}}+{{(10-6)}^{2}}}\] \[=\sqrt{9+16}\] \[=\sqrt{25}\] \[=5\Omega \]You need to login to perform this action.
