A conductor as a capacitor

Principle

The pupils should come to realise that metal objects such as an electroscope, induction plate and Faraday-beaker can store charges and can also transport them. They should observe that the amount of stored charge depends on the size and shape of the body.

Benefits

• Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

Conducting bodies can store charges. Show, using an electroscope, that conductors can store charges and that different bodies can store different amounts of charge.
