how much voltage can leyden jars handle?

Question

just wondering

and if you test them for capacitance with a farad meter will it show as if you were measuring a capacitor

Answer 1

Just like capacitors,the max voltage will vary. Yes, a leyden jar is a capacitor and should give you a reading on a farad meter.

A capacitor is technically 2 conductive plates with an insulator in the middle. There are millions of things that pose as capacitors, such as yourself(static electricity).

Answer 2

Voltage should be pretty high, probably limited more by the clumsiness of the attachments than the properties of the glass. And, yes, a capacity meter will read it as a capacitor. Expect a very small value. Small enough that the leads will seriously disturb the reading. But, yeah, it is a genuine capacitor.
