Science & Technology Museum, University of Patras Campus, Greece
Αn instrument for detecting and measuring static electricity or voltage.
A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate. The whole of this part of the electroscope is insulated from the body of the instrument. A glass front prevents air draughts but allows you to watch the behavior of the leaf.
The contact of charged objects with the terminal causes the transfer of loads to the metal sheets, so they diverge together.
The removal of the loads from the metal sheets or their elimination causes the metal sheets to return to their original position.
