• The theory and use of the Faraday Ice Pail. (This is adequately covered in the product description of
this section and in Demonstration 1.)
• The possible distortion of charge density due to improper use of the proof plane. (See the product
description section.)
• Residual charge may build up in the plastic insulator between the handle and disk of the proof plane
and charge producers. Make sure to ground these parts before any experiment.
• The capacitance of the electrometer must be considered when calculating the magnitude of a charge
from the voltage reading of the electrometer. (See Demonstration 3 for the procedure necessary to
determine the electrometer’s capacitance.)
By following the above principles and by practicing, the demonstrator should have a high degree of
success with the demonstrations and find their educational effect of great value
