Educational 50? Resistance Box Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12714

The Educational 50Ω Resistance Box is a physics laboratory apparatus used to introduce a known 50-ohm resistance into electric circuits for Ohm’s law, current control, resistance comparison, bridge methods, and practical electricity experiments. It is suitable for schools, colleges, physics labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Educational 50Ω Resistance Box from School Equipments India is intended for supervised physics and electrical laboratory demonstrations. The stated resistance capacity is 50 ohms. Exact construction, resistance steps, tolerance, terminals, coil material, power rating, case material, dimensions, weight, and calibration status must be confirmed from the final supplied product.

This apparatus helps students understand how resistance affects current in a circuit. It supports practical learning in electricity chapters, Ohm’s law verification, simple circuit construction, series-parallel comparisons, and resistance-measurement exercises. It should not be described as a certified calibration standard unless valid calibration documentation is supplied.

Key Features

• 50-ohm stated resistance: suitable for low-voltage school and college electricity practicals.
• Physics lab teaching aid: supports Ohm’s law, resistance, current, voltage, and power demonstrations.
• Known resistance value: helps students compare calculated and observed circuit behaviour.
• Circuit experiment support: useful for series circuits, parallel circuits, and resistance-comparison activities.
• Bridge-method compatibility: can support Wheatstone bridge practicals where the experiment design permits.
• 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 educational circuits, not direct mains use unless rated.

How to Use the Educational 50Ω Resistance Box

1. Check the product label, rating, 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 the approved low-voltage supply and observe ammeter and voltmeter readings.
6. Change resistance settings only within the confirmed operating limits.
7. Record readings and compare measured values with calculated Ohm’s law results.
8. Switch off the supply before disconnecting 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, and contact 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, or the case is damaged.

Frequently Asked Questions

What is an Educational 50Ω Resistance Box used for?

An Educational 50Ω Resistance Box is used to add a known 50-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 50Ω, 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?

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

Can students handle it directly?

Students can use it only under supervision. Power should be switched off during wiring, and the apparatus should be used within confirmed electrical ratings.
