4. What is a resonance circuit?  It is a rezistor, capacitor and inductor connection  When is resonance circuit in situation when is equal X C and X L then this situation called reverberation.  This circuit in reverberation is behave like active resistance. Series circuits Parallel circuits Kinds of resonance circuits

5. Connection of resonance circuits

6. Measuring scheme of resonance circuit

7. Important concepts resonance situation = reverberation Properties on resonance frequency Quality factor Charakteristics: - resonance curves: - simply - U=f(f)‏ - comparatively - U/U REZ =f(f/f REZ )‏

8. Important formulae Z=Rs+jωL-j1/(ωC)=Rs+j(ωL-1/(ωC)‏ f REZ =1/(2π√LC)‏ Q 0 =(ω 0 L)/R S0 Q 0 =1/(ω 0 CR S0 )‏ Q 0 =(f MAX +f MIN )/(f MAX -f MIN )‏ Z-impedance Rs-resistance L-inductance C-capacity f REZ -resonance frequency Q 0 -quality factor f MAX -maximum frequency f MIN -minimum frequency

9. Measuring procedure We calculated f REZ for given C a L in this circuit. We then connection circuit under scheme. We are set correct frequency on the generator that consistent with calculated value f REZ for C and L. We calculated U REZ √2 with help of U REZ (voltage at f REZ ) that consistent with decrease about 3 dB. We are set up frequency on the generator from f MIN (consistent with decrease about 3 dB) until f MAX (consistent with decrease about 3 dB) and measuring voltage. f REZ lie between f MIN and f MAX.
