The topic was actually meant to be 'resistance and electromagnetic oscillation'.
It is hard to translate specific words. I hope you understand what I meant.
I have an oscillating circuit. The data I know are:
Capacitance C=20*10^(-6) F
Inductance L=180*10^(-6) H
Attenuation (logaritmic decrement) = 1,4*Pi
What is resistance and period ?
There should be two periods, for example T and T_0.
If T_0=2*Pi*square root of(L*C), then what is T ?
I believe that it is possible to find the resistance using formula which relates damping factor to resistance and inductance. Damping factor = R/2L
Resistance should be 3,4 according to book.
