Decade of Resistance Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10644

The decade resistance box is a multi-range electrical resistance instrument used for resistor substitution, Ohm’s law demonstrations, circuit calibration and electronics experiments in school, college and STEM laboratories. It helps students and teachers select known resistance values without changing individual resistors repeatedly during a practical circuit activity.

Product Description

The Decade Resistance Box from Lab Glassware Manufacturer is a classroom electronics instrument designed for controlled resistance selection in low-voltage physics experiments. It is useful when a teacher or student needs to vary resistance in steps and observe the effect on current, voltage drop, lamp brightness or meter readings.

This instrument is suitable for physics laboratories, electronics training benches, STEM circuit kits and tender-based educational lab setups. Final resistance range, number of decades, step value, accuracy tolerance, terminal type and power rating should be confirmed from the approved datasheet before publication, quotation or procurement.

Key Features

• Multi-range decade resistance box for school physics and electronics experiments.
• Useful for Ohm’s law, series circuits, parallel circuits and resistor substitution work.
• Allows quick resistance selection without replacing loose resistors repeatedly.
• Suitable for use with meters, plug-in boards, power supplies and test leads.
• Helps students compare how different resistance values affect current and voltage.
• Designed for supervised low-voltage laboratory demonstrations.
• Supports practical circuit learning in Electronic Instruments and school physics labs.

How to Use the Decade Resistance Box

1. Check the confirmed resistance range, tolerance and power rating before use.
2. Keep the power supply switched off while connecting the resistance box.
3. Connect the decade resistance box in the required circuit using suitable terminals and leads.
4. Select the desired resistance value using the provided switches, knobs or dials.
5. Switch on the circuit and observe current, voltage or load behaviour with a compatible meter.
6. Change the resistance step by step and record the readings in the practical notebook.
7. Switch off the supply before disconnecting or changing the circuit layout.

Safety note: Do not exceed the confirmed current or power rating. Incorrect connection, overload or high voltage can heat the resistor network and damage the instrument.

Care & Maintenance

• Store the decade resistance box in a dry cabinet after use.
• Keep terminals clean, dry and free from corrosion.
• Do not use the instrument if switches, terminals or internal resistors appear damaged.
• Avoid overloading the unit; overheating can change resistance values or cause failure.
