Capacitors

Abstract

For my first capacitor I decided to use ordinary kitchen foil and sandwich cling film, purchased at the local supermarket. The capacitance might in fact end up signficantly higher than H P Friedrichs' due to the thinner materials used, particularly cling film which is very thin. This is important, since if I am to build an all-homebrew-component rig, I will need a power supply which will need to contain larger capacitances to obtain adequate smoothing. But I don't have time to make such a beautiful work of art as H P Friedrichs' version!
