Hi,(adsbygoogle = window.adsbygoogle || []).push({});

How can you prove that, in a damped RLC circuit, the logarithmic decrement equals the period times the damping factor:

[tex]\delta=T\zeta[/tex]

(I'm using [tex]\delta=\ln\frac{x(t_n)}{x(t_n+T)}\quad

\zeta=\frac{R}{2L}

[/tex] )

Thanks in advance!
