Pith-ball electroscope
Often the electroscope will have a pair of suspended pith balls. This allows one to tell at a glance whether the pith balls are charged. If one of the pith balls is touched to a charged object, charging it, the second one will be attracted and touch it, communicating some of the charge to the surface of the second … Visa mer The electroscope is an early scientific instrument used to detect the presence of electric charge on a body.
