Re: 0.1pF three-terminal capacitor

According to Kibble and Rayner's "Coaxial AC Bridges"
ISBN-0-85274-389-0) this is a Zickner capacitor.

Googling on "Zickner capacitor formula" threw up just one reference

http://www.google.com/search?q=cache:aevQ3O3DYtIJ:public.metapress.com/download/profiles/springerlink/0284/indexes/units/t000_units_a0245.pdf+Zickner+capacitor+formula&hl=en&lr=lang_nl%7Clang_en

which is to Springer Verlags "Landolt-Boernstein" which in turn gives
two references to Zickner G., both in Arch. Elektrotech (Berlin), one
to volume 38 page 1 in 1944, and the other to a joint paper with
H.Hoyer in 1957, from page 271.

I know rthat you've got access to academic liibraries, so you should be
able to take it from there - I could follow it up myself, but it
wouldn't be all that easy.
