His object now is to compare frictional with voltaic electricity.
Metals may be conveniently coated with compact copper to any desired thickness by means of voltaic electricity.
The first application of voltaic electricity to telegraphic purposes was made by Mr. Soemmering in 1809.
Acierage, coating a copper-plate with steel by voltaic electricity.
Again, voltaic electricity can be made to produce a spark, but under ordinary circumstances it scarcely amounts to anything.
The accordance between it and voltaic electricity is in this respect complete.
Such currents, and with magnetic properties, are always induced by powerful currents of voltaic electricity passing through wires.
The instrument offers the only actual measurer of voltaic electricity which we at present possess.
The parallel case of voltaic electricity has already been described (272, &c.).
I mean here by voltaic electricity, merely electricity from a most abundant source, but having very small intensity.
