RE: AC resonance circuit with DC electrolytic capacitors? (resonating, resonance?)

Not really.  As the lamp filament heats and cools, it causes filament
resistance to change, which slightly changes the resonant frequency of the
RLC circuit, which causes the current in the RLC to vary, which causes the
lamp to dim and brighten, which causes the filament resistance to vary,
which ... etc.

Thank you for the explanation, and very interesting;  a circuit pulsing in
and out of resonance.  Would this be in itself considered a form of
resonance?
