Resistance Box Electronic Type
Product Code : LSK-EAE-11114
Resistance Box Electronic Type (SKU LSK-EAE-11114) is a resistance box that puts a known resistance into a circuit for general physics laboratory experiments, offered in 50, 100, 500 and 1000 ohm versions. It suits electricity practicals in senior school and college physics labs. Science Lab Supplies builds this box at its own factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it directly to schools, colleges, tender contractors and distributors.

Applications and Experiments for the Electronic Resistance Box
The box supplies a known resistance wherever a circuit practical calls for one, so students can compare measured and expected values of current and voltage. It is useful school physics lab equipment in India for Ohm's law, series and parallel resistance and bridge balance work at senior secondary and undergraduate level.
- Class 10 and Class 11–12 physics: verifying Ohm's law with a known resistance, for example with the Ohms Law Apparatus.
- Series and parallel combinations: joining two versions, such as 100 Ω and 500 Ω, and checking the combined value against calculation.
- Bridge experiments: using the box as the known arm, with a centre-zero Galvanometer as the null detector.
- B.Sc. and diploma practicals: a reference value for checking a circuit before taking readings.
Run the circuit from a low-voltage source such as the Laboratory Battery Eliminator, and confirm the permitted current for your chosen version on the quotation before connecting a supply.
Standard Scope of Supply
The Resistance Box Electronic Type is supplied as a single unit in the resistance version you specify: 50, 100, 500 or 1000 ohms. Connecting leads, meters and a power source are not part of the unit and can be quoted separately if your laboratory needs them for its electricity practicals.
Packing, MOQ and Lead Time
A quotation can be prepared for one resistance box or for a mixed set of versions to equip every bench in an electricity lab. Each quotation from Science Lab Supplies lists the packing, delivery time and price for the quantity asked for, and meters or leads can be added to the same document.
With an Importer-Exporter Code in place, Science Lab Supplies is able to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. To ask for the price, write to us through the contact page, add the item to the enquiry cart, or read the lab tender page for tender supply.
Frequently Asked Questions
Which resistance values are available?
The electronic resistance box is made in four versions: 50 ohms, 100 ohms, 500 ohms and 1000 ohms. State the version, or a mix of versions, and the quantity of each when you request a quotation.
What is this resistance box used for?
It is designed for accurate and reliable results in general physics laboratory experiments, such as verifying Ohm's law, combining resistances in series or parallel, and providing a known arm in a bridge circuit.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. Each electronic resistance box is assembled at the company's factory in Saha, Ambala, India, so the quotation you receive is issued by the maker itself rather than by a reseller.
Can the box be ordered with other electricity apparatus?
Yes. Rheostats, meter bridges, galvanometers and other items from the Electrical and Electronics range can be listed on the same quotation, which helps when a school or college is equipping a complete electricity practical bench.
