    hello
    i was woundered if anybody could answer my question,
    how can we proove that the quality factor in resonant circuit is PROPORTION current of capacitor or inductor to input current?
    i mean why this formula is true I(c)/I(s)=i(l)/i(s)=q?

    The quality factor, Q, is the energy out divided by energy in. It's a dimensionless figure of merit. I would try an equation for the energy out over an equation for the energy in and show that all but the terms for current cancel.
