A) 2.0 ms
B) 3.0 ms
C) 4.0 ms
D) 5.0 ms
E) (e) None of the above
Correct Answer: E
Solution :
(e)Given, L = 12 mH \[C=1.2\,\mu F\] \[R=12\,\Omega \] Let the resonance \[{{X}_{L}}={{X}_{C}}\] \[\omega =\frac{1}{\sqrt{LC}}\] \[f=2\pi \frac{1}{\sqrt{LC}}\] \[\frac{1}{T}=\frac{1}{2\times 3.14\times \sqrt{12\times {{10}^{-3}}\times 1.2\times {{10}^{-8}}}}\times \frac{10}{100}\] \[\frac{1}{T}=133\] \[T=\frac{1}{133}\] \[T=7.5\,ms\]You need to login to perform this action.
