[Phys-L] Re: Electroluminescence Demo

The fact that the lamp connected to 110 V produces more light than when
an electrolytic cell is inserted in series is not surprising. Did you
measure the cell voltage? The glow on the electrons should depend on
that voltage only; presence of the 75 W light lamp is probably
irrelevant.

Experimenters who live off the land often use incandescents as a load limiter.
Until the oxide film forms on the aluminum electrodes, load limiting is needed.



Brian Whatcott Altus OK Eureka!
