What is an electroscope?

The electroscope is an early scientific tool used to determine whether a charge is present in the object. It is usually designed from a metal material that allows the electric charge to spread over the entire surface of the tool. This can be done by induction, which means that the item has a positive or negative charge without touching another already charged object. Electroscopes are unable to say whether the fee is positive or negative; They are only able to disclose information about how much fee is present.

This tool usually has swivel weapons that reveal whether a fee is present. The shoulders can remain vertical if no charge is present and moving when the machine receives a fee. The movement of weapons can also be influenced by items in the vicinity that contain a charge. He also formulated the theory on charged bodies and how the sustained stream of electricity between them can cause either to attract or repel. The device has been progress in Versorium design, a device for detecting static electricity.

The electroscope of gold leaves was invented by spiritual and scientist Abraham Bennet. Its equipment consisted of narrow gold leaves hanging from the rod surrounded by glass. When anything with electricity flowed near the rod, the leaves would move. If they were electrified with the same amount of fee, they would be reflected.

One of the most innovative electroscope uses occurred in the 18th century under scientists Marie and Pierre Curie. These scientists used a very sophisticated version of the tool to explore radioactivity. Radioactive materials ionize a substance in a charged electroscope. The ionization that takes place causes the charge of escape from the device faster than it would be normally. The measure at which the tool loses its charge is then measured and this speed is proportional to the intensity of radiation.
