Physics Laboratory Resistance Box 100? Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12717

The Physics Laboratory Resistance Box 100Ω is an educational electrical apparatus used to insert a known 100-ohm resistance into low-voltage circuits for Ohm’s law, current control, voltage-drop study, resistance comparison, and bridge experiments. It is suitable for schools, colleges, physics labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Physics Laboratory Resistance Box 100Ω from School Equipments India is intended for supervised physics and electricity practicals. The stated resistance capacity is 100Ω. Exact resistance steps, plug or dial arrangement, tolerance, power rating, terminals, case material, dimensions, weight, and calibration status must be confirmed from the final supplied product.

This resistance box helps students observe how resistance affects current when voltage is controlled. It supports practical work in Ohm’s law, series and parallel circuits, bridge-method experiments, resistance measurement, and basic electrical measurement. It should not be described as a certified calibration standard unless valid calibration documentation is supplied.

Key Features

• 100Ω stated resistance: suitable for low-voltage educational circuit experiments.
• Physics lab teaching aid: supports Ohm’s law, resistance, current, voltage, and power demonstrations.
• Known resistance value: helps students compare calculated values with observed meter readings.
• Circuit experiment support: useful for series circuits, parallel circuits, and resistance-comparison activities.
• Bridge-method application: can support Wheatstone bridge practicals where the resistance range and tolerance match the method.
• Construction to confirm: plug type, dial type, decade type, terminals, casing, and internal elements must be verified.
• Safe-use positioning: intended for supervised low-voltage laboratory circuits, not direct mains use unless rated.

How to Use the Physics Laboratory Resistance Box 100Ω

1. Check the product label, resistance value, terminal condition, and experiment instructions before use.
2. Keep the power supply switched off while making all circuit connections.
3. Connect the resistance box in the required circuit position using suitable laboratory leads.
4. Select the required resistance arrangement according to the plug, dial, or selector design.
5. Switch on only the approved low-voltage laboratory supply.
6. Observe ammeter and voltmeter readings without exceeding the confirmed rating.
7. Record readings and compare measured values with calculated Ohm’s law results.
8. Switch off the supply before disconnecting, changing settings, or storing the apparatus.

Safety note: Use only under teacher or laboratory-supervisor control. Do not overload the resistance box, connect it directly to mains voltage, or touch terminals during live experiments.

Care & Maintenance

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

Frequently Asked Questions

What is a Physics Laboratory Resistance Box 100Ω used for?

A Physics Laboratory Resistance Box 100Ω is used to add a known 100-ohm resistance into physics lab circuits for Ohm’s law, current control, resistance comparison, and bridge experiments.

Is it suitable for school physics laboratories?

Yes. It is suitable for supervised school and college physics laboratories when used with approved low-voltage circuit setups and teacher guidance.

Can it be used for Ohm’s law experiments?

Yes. The resistance box can be used in Ohm’s law experiments to study how current changes when resistance is introduced or varied in a circuit.

Is the resistance value fixed or selectable?

The stated product is 100Ω, but the exact selection method and resistance steps are not confirmed. Verify whether the supplied model is fixed, plug type, dial type, or decade type.

Does it include calibration documentation?
