A) \[3.07\times {{10}^{-8}}H\]
B) \[2.07\times {{10}^{-8}}H\]
C) \[4.07\times {{10}^{-8}}H\]
D) \[6.07\times {{10}^{-8}}H\]
Correct Answer: A
Solution :
The frequency of radio waves (speed c\[=3\times {{10}^{8}}\,\,m/s\]) transmitted \[f=\frac{c}{\lambda }=\frac{3\times {{10}^{8}}}{360}\] Frequency of series resonant circuit \[f=\frac{1}{2\pi \sqrt{LC}}orL=\frac{1}{{{(2\pi f)}^{2}}C}\] \[=\frac{1}{{{(2\times 3.14\times 8.3\times {{10}^{5}})}^{2}}\times 1.20\times {{10}^{-6}}}\] \[=3.07\times {{10}^{-8}}H\]You need to login to perform this action.
