Return to Electrostatics

Description:

This device is also used for a variety of demos to show the presence of electrostatic charge. When a charged rod is brought near the plate the needle will move. Scrape the rod on the plate and it will become charged and the needle will stay deflected. Bring an object of opposite charge and the deflection will decrease. A stainless steel sphere or a flat plate of zinc can be plugged in at the top. The zinc flat plate is used for the Photoelectric Effect demonstration.
