Question
A 0.5µF capacitor is discharged through a 10 millihenry inductor. Find the frequency of discharge.
Solution
Given:
C = 0.5 µF = 0.5 × 10-6 F
L = 10 mH = 10 × 10-3 H = 10-2 H
To find: Frequency (f)
Formula: f = `1/(2pisqrt"LC")`
Calculation:
From formula,
f = `1/(2 xx 3.142 xx sqrt(0.5 xx 10^-6 xx 10^-2))`
= 2.25 × 103 Hz
The frequency of discharge is 2.25 × 103 Hz.
