Damping in an RLC circuit

Hello,

I've got to prepare for a practical session and need some help with a problem: how (by what experiments) can you prove that the damping of a series RLC circuit depends on the value of the resistance (without basing oneself on any knowledge of the damping factor $$\zeta=\frac{R}{2L}$$).

Think in terms of energy. What is the energy loss of a current, I, passing through a resistance, R?

The energy loss is $$\Delta E=Ri^2\Delta t$$, right? But is there another way (based more on experiments) to show that $$\zeta\propto R$$ ?
