Laboratory Variable Resistor 10 Inch Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12721

The Laboratory Variable Resistor 10 Inch is a 10-inch variable-resistance physics laboratory apparatus used to control current in low-voltage circuits for Ohm’s law, resistance variation, voltage-drop study, current limiting, and circuit-training experiments. It is suitable for schools, colleges, physics labs, engineering labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Laboratory Variable Resistor 10 Inch from School Equipments India is intended for supervised physics and electrical laboratory practicals. A variable resistor changes resistance in a circuit so students can observe how current and voltage readings respond. The 10-inch size is taken from the product name; exact resistance range, current rating, power rating, winding material, tube material, slider mechanism, terminals, dimensions, and calibration status must be confirmed from the final supplied product.

This apparatus helps learners connect circuit diagrams with measurable electrical behaviour. It supports practical work on Ohm’s law, variable resistance, series circuits, voltage-current relationships, current control, and safe adjustment of laboratory circuits. It should not be described as a precision calibration instrument unless valid calibration documentation is supplied.

Key Features

• 10-inch laboratory format: suitable for classroom bench experiments where a compact variable resistor is required.
• Variable-resistance function: used to increase or decrease resistance during supervised circuit practicals.
• Current-control support: helps students observe how current changes when resistance is adjusted.
• Ohm’s law teaching aid: supports demonstrations involving voltage, current, resistance, and meter readings.
• Hands-on circuit training: useful for wiring practice, observation, data recording, and concept reinforcement.
• Construction to confirm: slider, coil winding, insulating tube, base, terminals, and contact design must be verified.
• Ratings to confirm: resistance range, current limit, power rating, and tolerance should be checked before procurement.

How to Use the Laboratory Variable Resistor 10 Inch

1. Check the product label, resistance range, current rating, terminals, and experiment instructions before use.
2. Keep the power supply switched off while making circuit connections.
3. Connect the variable resistor in the required circuit position using suitable laboratory leads.
4. Set the slider or control to the safe starting position recommended by the teacher.
5. Switch on only the approved low-voltage laboratory supply.
6. Move the slider gradually and observe ammeter and voltmeter readings.
7. Record readings at different resistance settings without exceeding the confirmed rating.
8. Switch off the supply before disconnecting, repositioning, or storing the apparatus.

Safety note: Use only under teacher or laboratory-supervisor control. Do not overload the variable resistor, connect it directly to mains voltage, touch terminals during live experiments, or continue use if heating, sparking, burning smell, or unstable readings occur.

Care & Maintenance

• Store in a dry, dust-free cabinet after practical sessions.
• Keep slider contacts, terminals, tube surface, and connection points clean and corrosion-free.
• Do not exceed the confirmed current, voltage, or power rating.
• Quarantine the apparatus if the slider is loose, winding is damaged, terminals overheat, or readings become unstable.

Frequently Asked Questions

What is a Laboratory Variable Resistor 10 Inch used for?

A Laboratory Variable Resistor 10 Inch is used to vary resistance and control current in low-voltage physics lab circuits for Ohm’s law, voltage-drop, and circuit-training experiments.

Is a variable resistor the same as a rheostat?

A rheostat is a type of variable resistor used for current control. In school physics labs, the terms are often used together for sliding resistance apparatus.

Can it be used for Ohm’s law experiments?

Yes. A variable resistor can be used in Ohm’s law experiments to adjust resistance and observe changes in current and voltage readings.

What does 10 inch mean in this product?

The 10-inch value is taken from the product name and should be confirmed as the physical size or tube length from the final supplied product.

What is the resistance range?

The resistance range is not confirmed. Add the exact ohm range, current rating, and power rating only after checking the product label or supplier documentation.

Does it include calibration documentation?

Calibration documentation is not confirmed. Do not claim a calibration certificate, test report, or accuracy class unless supplied with the final product.
