Demonstration electroscope with discharge electrode and two collectors

MACHINE TRANSLATION (not authorised yet)

A large (approx. 30 cm high) tiltable electroscope, sensitive and clearly visible during the experiments. The angle of deflection of the pointer depends on the charge that flowed from an electrically charged object, e.g. abonite stick rubbed with a piece of fur, applied to the ball bar. Additionally, two disc electrodes and an insulated rod are included. Equipped with an earthing socket (built-in), i.e. laboratory terminals for connecting an earthing cable.
