    What's the physical significance of Q factor?

    Re: Q factor hi, yes there are simillar. but parametrers are not the same Q (Low pass and High pass) filter=L/R=r/c=BW3dB/f0 but Q Band pass filter and band reject filter=BW3dB/f0 Q self= L/r

    Hoe to find current density ?

    first u must calculate R=ρl/A that A is surface and l=length of ur plate and ρ depend on quality of the plate. second calculate I=V/R. current will be obtained. regards.
