There is a nice treatise on Leyden jars on Wikipedia, where mention is made of a typical capacitance in jars of that era as 1 nF, which equals 1000 pF. By making just a few plausible assumptions about ...

Wimshurst machine with Leyden jars. Leyden jars and capacitors made of flat glass plates with foil remained in use for spark gap transmitters and medical electrotherapy equipment until the late 1800s.

Charge the Leyden jar again, as in the previous section. Remove the interior electrode using the plastic end of the wand and lift the glass insulator out of the exterior electrode. Use the wand to ...

Capacitors come in a variety of shapes and sizes, but they all have the same job: ... which came to be called a Leiden jar (though usually spelled with a “y” as Leyden jar).

The main course for the evening was roast turkey – which Franklin’s guests watched him electrocute with a Leyden jar (an early version of a capacitor, made with a glass jar and some metal ...

The transmitter required more than 50 Leyden jars for circuit capacitance. Dubilier's mica capacitor was sturdier, more efficient, smaller, and lighter than the Leyden jar.
