Electrical Resistance Box 500 Ohms Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12713

The Electrical Resistance Box 500 Ohms is a physics laboratory apparatus used to introduce known resistance values into electric circuits for Ohm’s law, resistance measurement, bridge experiments, current control, and practical electricity lessons. It is suitable for schools, colleges, physics labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Electrical Resistance Box 500 Ohms from School Equipments India is intended for supervised physics and electrical laboratory work. The stated resistance capacity is 500 ohms. The exact resistance steps, tolerance, coil material, terminal type, plug or dial arrangement, box material, dimensions, weight, and calibration details must be confirmed from the final supplied product.

This apparatus helps students connect circuit theory with measurable laboratory behaviour. It can be used to vary resistance, observe current changes, compare calculated and measured values, and build confidence in practical electricity experiments. It should not be described as a certified calibration standard unless valid calibration documentation is supplied.

Key Features

• 500 ohms stated capacity: suitable for school and college electricity practicals requiring controlled resistance.
• Physics lab application: supports Ohm’s law, current-resistance relationships, and circuit analysis experiments.
• Known resistance selection: allows students to introduce resistance values into a working circuit.
• Bridge experiment support: useful for Wheatstone bridge and resistance-comparison practicals where the method permits.
• Classroom demonstration value: helps teachers explain voltage, current, resistance, and power safely at low laboratory levels.
• Construction to confirm: plug type, dial type, terminals, case material, and internal resistance elements must be verified.
• Documentation-aware supply: tolerance, rating, calibration status, and operating limits should be checked before procurement.

How to Use the Electrical Resistance Box 500 Ohms

1. Check the label, resistance capacity, terminal condition, and teacher’s experiment plan before use.
2. Keep the power supply switched off while making circuit connections.
3. Connect the resistance box in the required circuit position using suitable leads.
4. Select the required resistance value according to the supplied plug, dial, or selector arrangement.
5. Switch on the low-voltage laboratory supply and observe current and voltage readings.
6. Change resistance values only within the rated operating limits.
7. Record observations and compare measured values with calculated results.
8. Switch off the supply before disconnecting the apparatus.

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

Care & Maintenance

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