Tutor description

An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.

The first electroscope, a pivoted needle called theversorium, was invented by British physicianWilliam Gilbertaround 1600.Pith-ball electroscopeA pith-ball electroscope, invented by British weaver's apprenticeJohn Cantonin 1754, consists of a small ball of some lightweight nonconductive substance, originallypith, suspended by asilkthread from the hook of aninsulatedstand. In order to test the presence of a charge on an object, the object is brought near to the uncharged pith ball.If the object is charged, the pith ball will be attracted to it.Gold-leaf electroscopeThe gold-leaf electroscope was developed in 1787 by British clergyman and physicistAbraham Bennet,as a more sensitive instrument than pith ball orstrawblade electroscopes then in use. It consists of a verticalmetalrod, usuallybrass, from the end of which hang two parallel strips of thin flexiblegold leaf.PROCESS INVOLVED IN USING THE ELECTROSCOPECharging by ConductionCharging by conduction involves the contact of a charged object to a neutral object. Suppose that a positively charged aluminum plate is touched to a neutral metal sphere. The neutr
