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. With the digital meters, rheostat, cells and switches, students can also run basic Ohm's law checks. It suits Class 12 physics and B.Sc. electricity practicals. Science Lab Supplies manufactures the kit at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the same factory team quotes schools, colleges, tender contractors and distributors.
Specifications
The table records the bridge kit's dimensions, meter ranges and lead lengths line by line. In short, a 1000 x 100 x 50 mm bridge unit carries a nickel-chromium wire and comes with a 0–20 V digital voltmeter, a 0–10 A digital ammeter, a 10 Ω, 5 A rheostat, three cells in a holder and five 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 centre-zero galvanometer for detecting balance can be added to the same 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. Send the class size and delivery town through the contact page, keep a shortlist in the enquiry cart, or review the lab tender page before you bid.
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.
Can a galvanometer be quoted with the bridge kit?
Yes. A centre-zero meter for finding the balance point, such as the Galvanometer 30-0-30 mA with colour-coded 4 mm terminals or the demonstration Galvanometer reading −500–0–500 µA, can be added to the same quotation.
Is Science Lab Supplies the manufacturer or a trader?
The 1000 mm bridge and its accessories are produced by Science Lab Supplies at its factory in Saha, Ambala, India. Because the manufacturer quotes directly, no middleman sits between your order and the workshop.
