THOSE who experimentalise with the usual form of gold-leaf electroscope must know well that the instrument requires a vast amount of preparation and drying before it is ready for use, and also that in ...
Editor's Note: The last electroscope I used employed gold leaves or pith balls to indicate charge, but here's an electronic version with no moving parts. Though one of our reviewers felt the design ...

I FIND that a very convenient way of charging an ordinary gold-leaf electroscope is to rub the charging rod with the glass bulb of a glowing carbon filament lamp. The leaf system becomes negatively ...
This diy electroscope circuit can precisely measure electrostatic charge. The charge to be measured is stored on C1 (a high quality MKT capacitor with a value of 1-2 μF). The voltage (U) across the ...
