Parallel Plate Capacitor Demonstration with Adjustable Distance

This Parallel Plate Capacitor Apparatus features two 120mm circular metal discs mounted on insulated supports that slide on an extruded aluminum section. The distance between plates and plate height are easily adjustable. Includes 3 dielectric materials: glass, cardboard, and Lucite. The apparatus measures approximately 11 inches long, 8 inches tall, and 6 inches wide. Easy to assemble with easy-to-read markings. Instructions included. Suitable for physics classroom demonstrations studying the principle of capacitance, its relationship with charge and voltage, and its dependence on conductor surface area.
