Dielectric Constant Kit

A dielectric is a material having low electrical conductivity in comparison to that of a metal. It is characterized by its dielectric constant. Dielectric constant is measured as the ratio of the capacitance C of an electrical condenser filled with the dielectric to the capacitance C0 of the evacuated condenser i.e.


A simple experimental set up is designed to measure the dielectric constant of solid samples in both range- LOW & HIGH.

The experimental set-up consists of :
- Main Unit having audio oscillator (1 KHz), digital voltmeter (0 – 9.99 V dc), standard capacitance and electronic circuitry.
- Dielectric Cells: 75 mm Gold plated brass discs (1 set) and 25 mm Gold plated brass discs (1 set).
- Samples : Low Range : Glass, Backelite
-                 Hi Range : PZT DISC
