Parallel Plate Capacitor

Product Code : SCL-EI-10708

Lab Glassware Manufacturer, based in Ambala, Haryana, and manufacturing scientific and educational laboratory equipment since 1982, supplies the Parallel Plate Capacitor to physics departments, STEM laboratories, and procurement teams across India and export markets including Serbia, Croatia, Bosnia and Herzegovina, and Montenegro, serving the wider Balkans region. 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. Plate diameter, plate material, separation range, scale reading, capacitance range, terminal type, dielectric accessories, and mounting design should be confirmed with Lab Glassware Manufacturer before final quotation, since adjustable capacitor models vary by experiment requirement.

Key Features

• Adjustable plate spacing: Allows students to vary the distance between capacitor plates during experiments.
• Capacitance demonstration aid: Helps show how plate separation and dielectric material affect capacitance.
• Parallel-plate design: Supports direct teaching of the standard capacitor model used in physics theory.
• Compatible with instruments: Can be used with suitable meters, voltage sources, and electronic instruments where rated.
• Useful for electrostatics lessons: Supports topics on charge storage, potential difference, and electric fields.
• Reusable lab apparatus: Suitable for repeated school and college practical sessions when handled correctly.

What's Included in the Kit

• 1 × Parallel plate capacitor main unit
• Pair of conductive plates
• Adjustable spacing mechanism or scale
• Terminals, leads, or connector sockets
• Dielectric sheets or sample plates
• Instruction sheet or experiment guide

Applications / Uses

• Demonstrating how capacitance changes with plate separation.
• Studying the effect of dielectric materials between capacitor plates.
• Showing the relationship between charge, voltage, and capacitance.
• Supporting experiments on electric field between parallel plates.
• Using with compatible meters, voltage sources, and general lab equipment.
• Teaching electrostatics and basic electronics in physics laboratories.

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, confirm the exact specifications, scale type, and included accessories of each with Lab Glassware Manufacturer before ordering, rather than assuming either listing is the more complete option. Both pair naturally with the Electrostatics Starter Kit for a broader electrostatics teaching sequence.

The company supplies laboratory glassware, scientific instruments, classroom kits, and physics teaching apparatus for educational and laboratory procurement requirements across India and export markets such as Serbia, Croatia, Bosnia and Herzegovina, and Montenegro.

Frequently Asked Questions

What is a parallel plate capacitor used for?
A parallel plate capacitor is used to demonstrate how capacitance changes with plate separation, dielectric material, plate area, charge, and voltage.

Is this apparatus suitable for school physics labs?
Yes. It is suitable for supervised school and college physics laboratories when used with compatible low-voltage equipment.
