Electroscope Charging By Induction
# 5A40.15




Description:

Touch the electroscope and bring a charged rod close. If the charged rod is negative, electrons from the electroscope will flow onto your body. Now remove your hand and then move the charged rod away. The electroscope will be left with a deficit of electrons giving it a positive charge. This can be confirmed by bringing the negative rod back close to the electroscope and watch the deflection go away.



Parts: electroscope, charged rods

Purchased/Built: purchased

Setup Time: 5 min.

Quant. in Demo Room: 2
