Adjustable Aepinus Air Capacitor for Electrical Experiments

Description

The Adjustable Aepinus Air Capacitor, also known as an air capacitor or variable parallel plate capacitor, is designed for supervised physics demonstrations involving capacitance, plate spacing and electrostatic charge behaviour. This apparatus uses two sets of square plates held in position by magnetic alignment, helping keep the plates parallel and correctly positioned in the friction slider blocks. The plate spacing can be adjusted from 1 mm to 120 mm as listed, allowing students to observe how capacitance changes as the distance between capacitor plates changes.

The product title lists an adjustable capacitance range of 2–250 pF, while the supplied description references approximately 300 pF down to 2 pF. Users should confirm the final published capacitance range before catalogue upload. The product title also references 200 and 283 mm square plates, while the description appears to reference plate dimensions that should be checked before final publication. Confirm the exact plate sizes before ordering where experiment accuracy is important. The design includes 4 mm sockets for electrical connection to each plate, supporting use with compatible laboratory leads and low-voltage electrostatics apparatus.

The circuit is listed as protected against accidental plate contact, and the sturdy feet provide good stability during classroom or laboratory demonstrations. This product is suitable for school science laboratories, university teaching laboratories and physics classrooms requiring a practical adjustable capacitor for electrostatics, capacitance and electric field demonstrations. Users should confirm plate size, capacitance range, connection method, compatible power source, required leads, experiment method and storage procedure before use.

Do not connect directly to mains electricity or high-energy supplies. Discharge the capacitor safely after use and before handling, adjustment or storage. Keep magnets and magnetic components away from sensitive electronics, magnetic storage media, pacemakers and other magnet-sensitive devices.

This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the adjustable Aepinus air capacitor only. Power supply, electrometer, leads, charge source, worksheets, meters, stands and additional electrostatics accessories are not included unless specified separately.
