WebWhat is an Electroscope? An electroscope is an early scientific instrument that is still used to detect the presence, magnitude and type (+ve or -ve) of electric charge on a body. It is composed of a metal disc, metal rod and two metal leaves in a glass body. The metal leaves deflect in the presence of electrical charges. WebAug 16, 2024 · 3) This attracts opposite charges from the neutral GLE to be brought upwards leaving the positive charge on the gold leaf. 4) Since there is an excess positive charge on gold leaf there would be repulsive forces (like charges repel), thus rising the gold leaf. 5) Then you place your finger on zinc plate to ground it.
