Ideal for classroom education, this model of the Wimshurst Machine provides the highest quality instrumentation at the best value. Two high resistance plastic and aluminum sheet plates are supported in two rigid uprights and driven by a belt in the opposite direction. Two leyden jars, made from glass and aluminum foil, act as condensers. All is mounted on a sturdy, durable base for years of use

The instrument can provide more than ten thousand electric potential differences. As a high-voltage static power in electrostatics experiments, it can be used to demonstrate the character and distribution of electric charge, and display the electric discharge in the power line as well as point discharge. It is an indispensable instrument both for colleges and high school laboratories.

Demonstrate storage of electrical charges! This unit is effective in helping students to understand the function of a dielectric and the buildup of static electricity. The inner and outer metal conductors are separated by a plastic insulator cup. These pieces slide easily in and out of one another. The inner conductor may be removed and the charge measured. When the conductors are replaced the charge is transferred back to them. 3 piece set.  
(6-1/2" x 3-1/4" x 3-1/4"; .5 lb).
