Giải thích các bước giải:
\(\begin{array}{l}
9.\\
f = \frac{1}{{2\pi \sqrt {LC} }}\\
100000 = \frac{1}{{2\pi \sqrt {0,{{1.10}^{ - 3}}.C} }}\\
C = 2,{533.10^{ - 8}}\\
11.\\
T = 2\pi \sqrt {LC} = 2\pi \sqrt {{{2.10}^{ - 3}}.0,{{2.10}^{ - 6}}} = 4\pi {.10^{ - 5}}\\
13.\\
T = 2\pi \sqrt {LC} \\
4\pi {.10^{ - 6}} = 2\pi \sqrt {L{{.200.10}^{ - 9}}} \\
L = {2.10^{ - 5}}
\end{array}\)
