An
electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body.

electroscope , works on similar principles but only indicates the relative magnitudes of voltages or
Kaynak: ElectrometerThe
electroscope has not acquired a net charge: the charge within it has merely been redistributed, so if the charge were to be moved away

electroscope) was the first non-working prototype (i.e. conceptual model) of a television or

electroscope and developer of an improved magnetometer .
