Decade Resistance Box Manufacturer,Supplier and Exporter in India

The Decade Resistance Box (Product Code: SLE/EAM/35) lets students dial in any whole-ohm resistance from 1Ω to 9999Ω, using four decades of 1% tolerance resistors. Physics teachers use it wherever a circuit needs a known, adjustable resistance — Ohm’s law, bridge circuits, potential dividers and meter-range work. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is a practical resistance box for India lab benches in schools, colleges and technical institutes.

Specifications

Typical Use

In an Ohm’s law experiment kit the box replaces a drawer full of loose resistors: students set a value, record current and voltage, change one decade and repeat, so the relationship between resistance and current emerges from a single tidy circuit. It also serves as the known arm of a Wheatstone or meter bridge, where the fine 1Ω steps let a class balance the bridge closely, and as a series resistor when extending the range of a meter. Wired through its 4mm sockets as a potential divider, it provides a chosen fraction of a supply voltage for sensor or component tests.

Before switching on, check that the current through the selected setting will stay below the 0.35A maximum and that dissipation stays within the 1W continuous rating — at low resistance settings even a modest supply voltage can exceed these limits. Setting all decades to a high value first and working downwards is a simple habit that protects the resistors.

Manufacturer

Jain Scientific Equipments Private Limited builds this decade box in Ambala, Haryana, and markets it to teaching laboratories under its ScienceLab brand.

Related Electricity and Magnetism Equipment

Apparatus that completes a resistance or Ohm’s law circuit with this box:

• Precision Variable Power Supply — an adjustable source for driving the circuit
• Digital Ammeter — reads the current so it can be kept under the 0.35A limit
• Digital Voltmeter — measures the voltage across the selected resistance
• Resistance Selector — a quicker option when only a few standard values are needed
• Stackable Leads — plug leads for wiring the circuit

Frequently Asked Questions

What range does the Decade Resistance Box cover?
From 1Ω to 9999Ω in 1Ω steps, set across four decades.

How close to the set value is the resistance?
The resistors are 1% tolerance, which is adequate for most school and college circuit work.

What current and power can it take?
Maximum current is 0.35A and the power rating is 1W continuous. Stay within both limits, especially at low settings.

How is it different from the Resistance Selector?
The selector switches between a fixed set of standard values, while this box gives every whole-ohm value across its range — better when you need fine adjustment, such as balancing a bridge.

Are connecting leads supplied?
Leads are not listed as part of this item. It uses 4mm sockets, so standard 4mm plug leads such as our Stackable Leads are suitable.

Can you provide a calibration certificate?
Please raise this with our team when you enquire so we can advise on what documentation is available for your order.

What should an institutional quotation request include?
The quantity, delivery address and any tender reference. Send them through our contact page; we supply across India and to international markets.
