A 2.0 mH inductor is connected in parallel with a variable capacitor. The capacitor can be varied from 100 pF to 200 pF. What is the minimum oscillation frequency for this circuit?

The oscillating frequency is from 251613.43 Hz to 388835.1 Hz

Explanation:

L = 2.0 mH = 2 × 10⁻³ H

c = 100 pF to 200 pf

π = 3.142

oscillating frequency

When c = 100 pf (100 × 10⁻¹²) :

oscillating frequency

Substituting values

When c = 100 pf, f = 388835.1 Hz

When c = 200 pf (200 × 10⁻¹²) :

oscillating frequency

Substituting values

When c = 200 pf, f = 251613.43 Hz

The oscillating frequency is from 251613.43 Hz to 388835.1 Hz
