Re: Corona bottles @ .001 mfd



Original poster: Gregory Hunter <tesla_39560@xxxxxxxxx>

When employed as salt water capacitors, 12oz (355ml)
beer bottles yield between 750-900pF each. A six-pack
is good for 5nF. A 12-pack is about right for 10nF.
Are you sure you only need .001uF? That isn't very
much.

.001uF = 1nF = 1000pF

for .001uF, you'd only need 1 or 2 beer bottles.
