Capacitance and Permittivity Kit
Product Code : JA-PLE-7964
The Capacitance and Permittivity Kit (SKU JA-PLE-7964) is a self-contained capacitance meter and parallel plate capacitor set for studying how capacitance depends on plate area, plate separation and the medium between the plates. This capacitance and permittivity kit for parallel plate capacitor experiments combines a reed relay switch, an integrated circuit current amplifier and a meter in one cabinet, with 0.25 m square capacitor plates, a Perspex sheet, spacers and two capacitors for series and parallel combinations. No other measuring instrument is needed.
Specifications
The measuring unit uses a reed relay switch with its AC supply and an integrated circuit current amplifier that produces an output current proportional to capacitance, read on a 0-100 microammeter, with a sensitivity of about 0.1 nF and linearity better than 1% of full-scale deflection.

Experiments with the capacitance and permittivity kit
The kit is used in electrostatics practicals to show, with direct meter readings, how capacitances add in series and in parallel and how the capacitance of a parallel plate capacitor changes with overlap area, plate separation and the dielectric between the plates.
- Series and parallel combination of capacitances using the two capacitors
- Variation of capacitance with the area of overlap of the parallel plates
- Variation of capacitance with the distance between the plates, set with the spacers
- Effect of the medium between the plates, comparing air with the Perspex sheet to estimate the permittivity of Perspex
