What are some applications of electroscope?(School project)


1) It can be used to detect high Voltage. When charged, the leaves separate because like charges repel.

2) It can be used to detect radioactivity. When subjected to strong ionizing radiation, it will discharge the device, so the leaves will fold together since the charge bleeds off. It is assumed that the insulation is perfect. Also, humidity in the air will tend to bleed off the charge over time. - it is not a very sensitive radioactivity detector - do NOT count on it to warn you of dangerous levels of radiation!

3) For determining the polarity of a high Voltage. (Charge it with the unknown, then bring it close to another high Voltage of known polarity and see if the leaves stay apart or if they collapse.)
