This unit is effective in helping students understand the function of a dielectric and the build-up 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.
