Resonance and the laboratory work
Answers are for parents and teachers.
1
L = 0.2 H and C = 5 μF. What is ω_res in rad/s?
1000
2
At resonance Uₘ = 12 V and R = 6 Ω. What is Iₘ in A?
2
3
In this circuit X_L = 90 Ω. What is U_L in V?
180
4
If the capacitance of a circuit is increased 9 times, by what factor does the resonance frequency change?
It decreases 3 times.
5
Why is the resonance curve narrow and tall when R is small?
At resonance Z = R is very small and the current large; once the frequency shifts, the reactance quickly exceeds R.
