The Parallel Plate Capacitor Apparatus is used to study the principle of capacitance its relationship with charge and voltage and its dependence on surface area of conductors.The apparatus consists of two 120mm circular metal discs mounted on insulated supports that slide on an extruded aluminum section. The distance between the two plates and the height of the plates are easily adjustable.The apparatus includes 3 sheets of dielectric materials. Dielectric materials includes are glass cardboard and Lucite.The apparatus is easy to assemble and the markings are easy to read.Dimensions: (L)280mm x (H)203mm x (W)152mmInstructions are included.
