· The gold leaf electroscope has been used by physicists for hundreds of years. It indicates the presence and magnitude of a charge through the application of charge to a copper top plate connected through a stem to two pieces of gold leaf. The movement of one piece of gold leaf away from the other shows that the electroscope is charged.

: Wedgwood TutorsA Gold Leaf Electroscope is an instrument for the detection and testing of small electric charges. It is a metal disc connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate. The electroscope is insulated; a glass in front prevents air draught but the behaviour of the leaf can be seen.

The gold leaf electroscope invented in 1786 by Abraham Bennet (1750-1799) included two "earthing strips". Ganot notes that "The delicacy of this electroscope may be increased by adapting to the foot of the apparatus two metal rods, terminating in knobs; for these knobs, being excited by induction from the gold leaves, react upon them."

: Philip RussellThe electroscope can be used to demonstrate that a small current is flowing in a circuit – for example in experiments to show the ionisation of the air. Using the hook rather than the plate makes the electroscope more sensitive to small amounts of charge. A charge of around 0.01 pC will cause a noticeable deflection of the gold leaf.
