Answers
Given info : A 20/π μF of a capacitor is discharged through a 50/π mH of an inductor.
To find : The frequency of oscillator is...
solution : inductance of the inductor, L = 50/π mH
conductance of the conductor, C = 20/π μC
using formula,
angular frequency of oscillator is given by, ω = 1/√(LC)
= 1/√{50/π × 10¯³ H × 20/π × 10¯⁶}
= 10³π rad/s
we know, angular frequency = 2π × frequency
⇒frequency = ω/2π = (10³π)/2π = 500 Hz
Therefore the frequency of oscillator is 500 Hz.
