What is an electroscope used for?

An electroscope is a special meter for observing an electrical charge. The principle of operation is the interaction between like-charged particles, namely, they repel each other.

When a charged object touches the electrode, the charges descend down the electrode and stop at the leaves of the same name. Those, in turn, move away from one another.
