f=(1/2π √LC) ∴ f=(1/2× 3.14√0.5× 10-3× 20× 10-6) =(1/2× 3.14× 10-4) ≈ 1600 Hz.

Q. A circuit consists of an inductance of 0.5 mH and a capacitor of $20 μ F .$ The frequency of the LC oscillations is approximately :

400 Hz

88 Hz

1600 Hz

2400 Hz

$f = \frac{1}{2 π L C}$ $∴$ $f = \frac{1}{2 \times 3.14 0.5 \times 10 ^{- 3} \times 20 \times 10 ^{- 6}}$ $= \frac{1}{2 \times 3.14 \times 10 ^{- 4}}$ $\approx 1600 Hz .$
