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.)
