About This Product
Touching a charged glass or ebonite rod to the disc makes the leaves spread apart as like charges repel; bringing the rod close without contact, earthing the disc briefly and then removing the rod leaves the electroscope charged with the opposite sign. Students use it to show charging by friction, conduction and induction, and touching the disc or the earthing screw resets it.
Frequently Asked Questions
How is the Gold Leaf Electroscope STEM Lab discharged?
Touch the brass disc or the earthing terminal with a finger; the charge flows to earth and the leaves hang flat again.
Which terminals are supplied?
A 50mm brass disc and a 25mm brass sphere, which can be swapped on the rod.
