Question

The carrier frequency generated by a tank circuit containing $1nF$ capacitor and $10\mu H$ inductor is

• A. $1592Hz$
• B. $1592MHz$
• C. $1592kHz$
• D. $159.2Hz$

Answer 1

Answer: (C)

$v=\frac{1}{2\pi \sqrt{LC}}$
$=\frac{1}{2\times 3.14\sqrt{10\times 10^{-6}\times 1\times 10^{-9}}}$
$=1592kHz$
