PARALLEL PLATE CAPACITOR APPARATUS

Parallel Plate Capacitor Apparatus (Demonstration)

•  This Parallel Plate Capacitor apparatus measuring approximately 280mm long x 200mm tall x 150mm wide.
•  Easy to assemble which comprises 3x sheets of dielectric materials:
Glass  |  Cardboard  |  Lucite.
•  Study the principle of capacitance and its relationship with charge, voltage and dependence on surface area of conductors.
•  Contains two 120mm circular metal discs mount on insulated slide supports connected to an extruded aluminium section.
•  The distance between the two plates and the height of the plates are easily adjustable.

(Wikipedia excerpt: ..."The simplest model of a capacitor consists of two thin parallel conductive plates each with an area of A {\displaystyle A} separated by a uniform gap of thickness d {\displaystyle d} filled with a dielectric of permittivity ε {\displaystyle \varepsilon }. It is assumed the gap d {\displaystyle d} is much smaller than the dimensions of the plates. This model applies well to many practical capacitors which are constructed of metal sheets separated by a thin layer of insulating dielectric, since manufacturers try to keep the dielectric very uniform in thickness to avoid thin spots which can cause failure of the capacitor. ...")
