Winston Bridge Kit
Product Code : SCL-PL-11822
Winston Bridge Kit (SKU SCL-PL-11822) is a Wheatstone bridge set built around a 1000 mm Ni-Cr wire, used to find an unknown resistance by balancing two ratio arms. Digital meters, a rheostat, cells and switches let students also run basic Ohm's law checks. It suits Class 12 physics and B.Sc. electricity practicals. Science Lab Supplies manufactures it at its own Ambala factory (Plot 448, HSIIDC Industrial Area, Saha) and supplies schools, colleges, tender contractors and distributors without intermediaries.
Specifications
The bridge unit measures 1000 x 100 x 50 mm and carries a nickel-chromium resistance wire. It is supplied with a 0–20 V DC digital voltmeter, a 0–10 A DC digital ammeter, a 10 Ω rheostat rated 5 A, three cells in a battery holder and five circuit switches.

Applications and Experiments for the Winston Bridge Kit
A slide-wire Wheatstone bridge compares an unknown resistance with a known one by finding the point of zero current along a uniform wire. The kit fits the metre bridge experiments in NCERT Class 12 physics practicals and the bridge exercises of B.Sc. and diploma electricity labs.
- Class 12 physics: resistance of a given wire and its resistivity using a metre bridge.
- Class 12 physics: laws of combination of resistances in series and parallel.
- Ohm's law checks with the digital voltmeter, ammeter and rheostat.
Standard Scope of Supply
The set comprises the 1000 mm Ni-Cr bridge unit, the digital voltmeter and ammeter, a battery holder with three cells, the 10 Ω rheostat, five switches and sixteen 4 mm flexible leads. A galvanometer is not part of the set; one for detecting balance can be added to the quotation.
Packing, MOQ and Lead Time
Pricing is available for one bridge kit or a batch for a whole practical class. Your quotation confirms the packing, delivery time and price for the number requested, and resistance boxes, galvanometers or a potentiometer kit can be listed alongside.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Contact the sales team through the contact page, save a shortlist in the enquiry cart or read the lab tender page before bidding.
Frequently Asked Questions
Is the Winston Bridge Kit the same as a Wheatstone bridge?
Yes. It is a slide-wire Wheatstone bridge, often called a metre bridge, with a 1000 mm Ni-Cr wire for finding unknown resistances by the balance method.
Does the kit include a galvanometer?
No, a galvanometer is not part of this set. The Galvanometer 30-0-30 mA, or the Galvanometer Kit with its 30-0-30 meter, can be added to the same quotation.
Is Science Lab Supplies the manufacturer or a trader?
It manufactures the kit. Science Lab Supplies builds the bridge at its factory in Saha, Ambala, India, so each quotation comes from the maker instead of a middleman.
