Electroscope
An electroscope is an instrument that is used to detect the presence and magnitude of electric charge on a body.This teaching aid is made to teach students about transfer of charges. This device is used to detect charges.When a charged object is brought near the metal rod, both strips repel each other and resemble an inverted V. The strips repel each other because they have acquired a like charge. When the strips have a like charge and separate, the electroscope becomes charged. If an object with the opposing charge is brought near the metal rod, the strips of aluminium will hang straight down. The strips no longer repel each other because the charge has been neutralized.
