Ответ:
The value of the inductance is 0.955 mH
Explanation:
Given;
frequency of the oscillator, f = 18 kHz = 18,000 Hz
the peak current, I₀ = 70 mA = 0.07 A
the root mean square voltage,
= 5.4 V
The root mean square current is given as;
Inductive reactance is given by;
Inductance is given by;
L = 0.955 mH
Therefore, the value of the inductance is 0.955 mH
