It will be observed that I have produced one cell which was 337.5 times as conductive in hazy sunlight as in dark.
Most of the transmitters in use, however, depend solely upon carbon as the conductive material of the variable-resistance element.
Hence the deflection produced by these metals is due to their diamagnetic, and not to their conductive capacity.
In the photophone the conductive wire has already been dispensed with, and a ray of light is used in its place.
That is, the neurones are laid in conductive series, the far end of one apposed to the near end of its precursor.
These particles are the actual agents of conduction of electricity, since the gas when filtered ceases to be conductive.
