Question

In the given circuit, the resonant frequency is

• A. 15.92 Hz
• B. 159.2 Hz
• C. 1592 Hz
• D. 15910 Hz

Answer 1

Answer: (C)

1592 Hz

Answer 2

Resonant frequency of an circuit is given by
$f=\frac{1}{2 \pi \sqrt{L C}}$
$=\frac{1}{2 \pi \sqrt{0.5 \times 10^{-3} H \times 20 \times 10^{-6} F}}$
$=1592\, Hz$
