手作り箔検電器の教育的活用

Abstract

Leaf electroscopes are easily made by hand and have high sensitivity to static electricity They are useful for educational experiments in electro-physical phenomena. Very simple leaf electroscope using tissue paper (facial paper) and that using aluminum foil for accurate measurement are presented. It is shown that hand-made leaf electrometers can be applied to the experiment of frictional-electrification phenomena, and measurements of electric resistance and electrostatic capacity.
