As late as 1820 the European philosophers were trying to construct a telegraphic system based upon two ideas, announced a long time before, to wit, the use of static or frictional electricity, and a wire for every letter.
Previous to 1750 Franklin had written a paper in which he showed the likeness between the lightning spark and that of frictional electricity.
For a period of 2300 years, from Thales to Franklin, but little or no progress was made beyond the further development of the phenomena of frictional electricity--the most important invention being that of the Leyden jar.
About 1748 Franklin succeeded in firing spirits by means of a wire across the Schuylkill River, using, as all the other experimenters had done, frictional electricity.
As the difference of potential is kept up by the continued chemical action, the current is continuous, and not simply instantaneous, as in discharges of frictional electricity.
The ebonite sheet became electrified or charged; and as the electrification was produced by friction, we may say that the action of the ebonite indicated the presence of frictional electricity.
While the ebonite sheet alone, or a good hard-rubber comb, may be used for many experiments in frictional electricity, the sparks produced are small, and the ebonite has to be electrified as often as it is discharged.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "frictional electricity" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
