Answer:
- The resistance of the circuit is 1250 ohms
- The inductance of the circuit is 0.063 mH.
Explanation:
Given;
current at resonance, I = 0.2 mA
applied voltage, V = 250 mV
resonance frequency, f₀ = 100 kHz
capacitance of the circuit, C = 0.04 μF
At resonance, capacitive reactance () is equal to inductive reactance (),
Where;
R is the resistance of the circuit, calculated as;
The inductive reactance is calculated as;
The inductance is calculated as;
