Re: Vintage French Doorbell - Surely not 220V AC working!!!
I suspect that this is for 220 volt AC supply, with a DC resistance of 1,000 ohms, a total AC impedance of about 2,200 ohms seems reasonable.
That would mean an input current of about 100ma, and a resistive dissipation of some watts, which would be fine for short term use.
Alternatively it might be for 127 volt mains, of which there was once a lot in France.
Possibly for some industrial or railway use rather than a domestic door bell.
