Question

How does the Gold Leaf Electroscope work?

Answer 1

The gold leaf electroscope has a very very thin piece of gold foil (called gold leaf) fixed at the top to a piece of copper.The copper has a large round top, called the cap.The whole thing is put inside a glass case,to stop air blowing the delicate gold leaf around.
The piece of copper goes through insulation in the top of the glass case, so that any charge on the gold leaf cannot escape.The picture first shows an uncharged gold leaf electroscope.

Charge can be transferred to the electroscope by wiping the charged object across the cap. The charge flows over the conducting copper and gold, and the gold leaf rises as it becomes repelled by having the same charge as the copper.The picture second shows a charged gold leaf electroscope.
