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.
