Leyden Jar Set

Leyden Jar Set

A Leyden Jar Set typically consists of 3 pieces:

one plastic jar, nested between two fairly snugly fitting metal cups.

When the jar is charged with a high voltage and carefully dismantled, it is discovered that all the parts may be freely handled without discharging the jar. If the pieces are re-assembled, a large spark may still be obtained from it.

It was the original form of a capacitor (originally known as a “condenser”).
