Parallel Plate Capacitor
Product Code : SCL-EI-10708
This apparatus is used to demonstrate capacitance, plate separation, dielectric effect, charge storage, and the voltage relationship between two conductive plates in school and college physics laboratories.
Quick Answer: The Parallel Plate Capacitor is a variable-spacing demonstration capacitor that lets students vary plate separation and insert a dielectric sheet while measuring capacitance and voltage response, connecting classroom electrostatics theory to a hands-on, adjustable apparatus.
The Parallel Plate Capacitor from Lab Glassware Manufacturer is designed for electricity and electrostatics practicals where students study a variable parallel-plate capacitor. It supports demonstrations involving plate area, spacing, dielectric insertion, stored charge, potential difference, and the basic construction of capacitors. This product belongs to the physics lab equipment category and is intended for supervised educational use.
Key Features
- Adjustable plate spacing: Allows students to vary the distance between capacitor plates during experiments.

How to Use the Parallel Plate Capacitor
- Place the capacitor on a clean, dry, stable laboratory bench.
- Check the plates, spacing mechanism, terminals, and leads before use.
- Set the initial plate spacing according to the experiment guide.
- Connect the apparatus only to an approved low-voltage supply or capacitance meter.
- Change the plate separation gradually and record the measured capacitance or voltage response.
- Insert a dielectric sheet if supplied, then compare the reading with the air-gap result.
- Switch off and discharge the capacitor safely before changing connections or handling the plates.
Safety note: Do not connect the Parallel Plate Capacitor directly to mains electricity. Discharge the plates after use, avoid touching charged terminals, and use suitable safety protective wears during broader electrical demonstrations.
Care & Maintenance
- Keep the capacitor plates clean, dry, and free from dust or fingerprints.
- Do not scratch, bend, or dent the plates, as this can affect alignment.
- Store dielectric sheets flat and away from moisture.
- Replace damaged terminals, leads, or adjustment parts before reuse.
Parallel Plate Capacitor vs. Adjustable Plate Capacitor: Confirming Which Fits Your Order
Lab Glassware Manufacturer also lists a separate Adjustable Plate Capacitor covering the same variable parallel-plate capacitance topic. The supplied catalogue data does not specify exactly how the two listings differ — for example, whether one offers a wider plate-separation range, a digital scale, or additional dielectric samples. If you are choosing between the two, Both pair naturally with the Electrostatics Starter Kit for a broader electrostatics teaching sequence.
