Quick Answer: These Coaxial Cylinders form a cylindrical capacitor: two conductive cylinders share one central axis, and capacitance is measured between them. The apparatus is used in electrostatics practicals on capacitance, electric fields and dielectrics.

Key Features
Two conductive cylinders arranged on the same central axis
Terminal connections for a capacitance meter, circuit or measuring instrument
Dielectric material can be placed between the cylinders for comparison
Shows how conductor geometry, separation and length affect capacitance
About This Product
After checking that the cylinders are aligned, students read the capacitance between them, insert a dielectric and read it again. Comparing the two values shows the effect of the dielectric medium, and the coaxial layout helps explain how charge and electric field are distributed between the conductors.
Frequently Asked Questions
How is the effect of a dielectric shown with the Coaxial Cylinders?
Capacitance is recorded with nothing between the cylinders and again after a dielectric material is inserted, and the two readings are compared.
