Original poster: "S&JY" <youngs@xxxxxxxxx> 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.
Something strange in this...If the capacitor, inductor, and lamp are in series, the frequency where there is maximum voltage over the lamp does not depend on its resistance. Maybe with a different connection this can work. With the lamp in parallel with the capacitor, and adding some resistance in the inductor, the circuit has a structure similar to a well known chaotic circuit, and may
work as a chaotic resonator. (Something to verify.) Antonio Carlos M. de Queiroz
