Electroscope - Wikipedia

An electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage.The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are ...
