MOSFET Electroscope

MOSFET Electroscope detects static charge. In a very dry day we all experience the effect of electric charge on our body by some means. Suppose you are sitting on a sofa wearing some woolen cloth, when you are standing, your body becomes electrically charged, now if you touch a doorknob or other metal object you will experience an electrical shock. When our body or any other object is electrically charged, it is possible to detect with this electroscope. I am going to show you how it works.
