It indicates that Franklin had subjected them to a scrutiny hardly less close than that which he had fixed upon the Leyden jar.
This is an example of the “quick discharge” of a Leyden jar.
Let us look at the familiar illustration of charging a Leyden jar.
Next, he took his Leyden jar and collected the electricity in that.
Then he connected the crown by a long wire with the Leyden jar.
Not less than three professors invented the famous Leyden jar in the year 1795.
He believed that the electricity in the bottle, or Leyden jar, was the same thing as the lightning we see in a thunder-storm.
The discharge of a Leyden jar or of another condenser sets up ether waves that have the speed of light.
In order to collect the electricity thus generated a vessel called a Leyden jar is used.
Before he made this discovery, men of science had learned how to store up electricity in what is called a Leyden jar.
1755, phial used for accumulating and storing static electricity, from Leyden (modern Leiden), city in Holland; so called because it was first described (in 1746) by physicist Pieter van Musschenbroek of Leyden (1692-1761). The place name is said to be from Germanic *leitha- "canal."
|Leyden jar |
An early device for storing electric charge that uses the same principle as a modern capacitor. It consists of a glass jar with conductive metal foil covering its inner and outer surfaces, with the glass insulating these surfaces from each other. The inner surface is charged (by an external source) through an electrode penetrating the top of the jar; the inner and outer foil layers can then hold an equal and opposite charge.
