ThermalRunaway said:R1 is not in parallel with R2, it is in series with R2. However, once the capacitor becomes resistive, it is then in parallel with R2 which means the "R" variable in the equation is no longer a constant.
lord loh. said:I guess the inductor, in practical cases has some losses and needs soem energy to be fed into the tank circuit to compensate these losses. So I believe that there is no way to create an osicllator without an amplifier. Tell me if I am wrong.
Do you mean sustained oscillation when you say resonance? or do you count transient responses as well?
Now that 3iMaJ, mentioned the Laplace Transform, I am recollecting a few things.

See the Wikipedia topic "RLC Circuit".Do you mean sustained oscillation when you say resonance? or do you count transient responses as well?

Laplace transforms? Oscillation? Guys, this is a DC circuit. No need for AC analysis, and there should be no oscillation, simply decay.
