electroscope's Usage Examples:

This insulation, however, is not sufficiently good for an electroscope intended for the detection of radio-activity; for this purpose .


condenser plate P attached to the outer case, then this substance bestows conductivity on the air between the plates P and P', and the charge of the electroscope begins to leak away.


If whilst holding the ebonite sheet over the tray the latter is also touched with an insulated brass ball, then this ball when removed and tested with the electroscope will be found to be negatively electrified.


In the use of all these electroscopic instruments it is essential to bear in mind (as first pointed out by Lord Kelvin) that what a gold-leaf electroscope really indicates is the difference of potential between the gold-leaf and the solid walls enclosing the air space in which they move.


To detect electrification it is best to charge the electroscope by induction.


If the ball is discharged and touched against the other tray, and then afterwards against the previously charged electroscope, the leaves will collapse.


In the interior no trace of electric charge could be found when tested by electroscopes or other means.


well as of discharging a charged electroscope (Com.


In a dry atmosphere sulphur or amber is an early perfect insulator, and hence if the air in the interior of the box is kept dry by calcium chloride, the electroscope will hold its charge for a long time.


If an insulated brass ball is touched against the first tray and then against the knob or plate of the electroscope, the gold leaves will diverge.


In connexion with the modern study of radioactivity, the electroscope has become an instrument of great usefulness, far outrivalling the spectroscope in sensibility.

If, without removing the electrified body, the plate or knob of the electroscope is touched, the leaves collapse.
