Adjustable Plate Capacitor

Product Code : SCL-EI-10682

The Adjustable Plate Capacitor is a physics laboratory electrostatics apparatus manufactured and exported by Lab Glassware Manufacturer, Ambala, Haryana, India, a manufacturer and exporter of laboratory glassware, scientific instruments, and STEM teaching apparatus since 1982. It is used to study capacitance, plate separation, charge storage, electric fields, and dielectric effects, and is supplied to schools, colleges, and STEM laboratories across India and to export buyers in countries including Sweden, Norway, Denmark, and Finland, and across the Northern Europe region.

Quick answer: An Adjustable Plate Capacitor is a parallel-plate capacitor whose plate spacing can be varied, letting students observe directly how capacitance changes with plate separation, plate area, and the dielectric material between the plates. It is typically used together with a coulombmeter or capacitance meter so that the effect can be measured rather than only described. Capacitance range, plate diameter, insulation material, and included accessories vary by unit — check the specific listing before ordering.

Technical Specifications

Applications / Uses

• Studying capacitance in a parallel-plate capacitor
• Demonstrating the effect of plate separation on capacitance
• Comparing air and dielectric materials between capacitor plates
• Explaining charge storage and potential difference
• Using with coulombmeters, capacitance meters, or electrostatics apparatus where compatible
• Supporting school physics practicals, STEM activities, and electrostatics demonstrations

How to Use the Adjustable Plate Capacitor

1. Confirm the capacitance range, voltage limit, terminal layout, and approved measuring instrument before use.
2. Place the capacitor on a dry, stable, insulated laboratory bench.
3. Inspect the plates, adjustment mechanism, terminals, insulation, and leads for damage.
4. Set the starting plate separation according to the experiment method.
5. Connect the capacitor to a suitable meter or approved low-energy electrostatics apparatus.
6. Change the plate spacing gradually and record the capacitance or charge reading.
7. Insert a dielectric sheet if supplied and compare the reading with the air-gap result.
8. Discharge the capacitor safely before touching plates or changing connections.

Safety note: Use only with approved low-energy classroom apparatus unless the voltage rating is verified. Do not connect the capacitor directly to mains electricity, high-voltage supplies, or charged circuits without confirmed insulation, discharge procedure, and teacher supervision.

Care & Maintenance

• Store the capacitor dry and protected from dust, corrosion, and impact.
• Keep plates clean, flat, and free from fingerprints or conductive contamination.
• Do not bend plates, force the adjustment mechanism, or overtighten terminals.
• Remove from use if insulation cracks, plates deform, terminals loosen, or readings become unstable.

Three Capacitor Formats for Different Lessons

Lab Glassware Manufacturer's Electronic Instruments range includes three distinct capacitor products, and choosing the right one depends on what the lesson needs to show. The Adjustable Plate Capacitor is a variable-spacing parallel-plate design, best suited to demonstrating how capacitance changes with plate separation and dielectric material. The One-F Capacitor Board is a fixed-value board-mounted capacitor for circuit-building lessons, and the Plug-In Capacitor Module is a modular plug-in component for the plug-in circuit-building system. For measuring the charge or capacitance a plate capacitor produces, pair it with a Coulombmeter, as the source specification for this product explicitly notes compatibility.

Why Choose Lab Glassware Manufacturer

Lab Glassware Manufacturer designs, manufactures, and exports laboratory glassware, scientific instruments, physics and electronics teaching apparatus, science kits, and STEM models from Ambala, Haryana, India, with a manufacturing history dating to 1982. Its Electronic Instruments range includes capacitor, electrostatics, circuit, power supply, measuring, and physics teaching apparatus, supplied to schools, colleges, universities, research institutions, and export buyers, including institutional buyers across Sweden, Norway, Denmark, Finland, and the broader Northern Europe region. The company holds ISO 9001 and ISO 13485 certification; any other certification claim for a specific product should be confirmed directly with Lab Glassware Manufacturer before it is used in tender or catalogue documentation.

Frequently Asked Questions

What is an Adjustable Plate Capacitor used for?
An Adjustable Plate Capacitor is used to study capacitance, charge storage, electric fields, plate separation, and dielectric effects in physics experiments.

What is the capacitance range?
The capacitance range is not confirmed in current product data. Schools should confirm the value from the product label, datasheet, or supplier before ordering.

Does it include dielectric plates?
Dielectric plate inclusion is not confirmed. Schools should confirm whether dielectric sheets are supplied with the final product before ordering.

Can students vary the plate separation?
Yes. The product is described as adjustable, so variable plate spacing is the expected demonstration feature; schools should confirm the exact adjustment range before publishing catalogue claims.

Can it be used with a Coulombmeter?
Yes. It can be used with a compatible Coulombmeter or capacitance meter if the voltage, charge level, and input ratings are suitable.

Is it suitable for school physics labs?
Yes. It is suitable for supervised school and college physics practicals on capacitance, charge storage, and electrostatics.
