Wheatstone Bridge
Product Code : JA-EE-7586
The Wheatstone Bridge (SKU JA-EE-7586) is a slide-wire bridge for finding an unknown resistance by balancing it against a known one, a standard practical in senior-school and college physics. A 24 SWG constantan wire is stretched along the top of a metre scale marked in mm and cm, broad heavily plated brass strips are mounted on a polished hardwood base, and the terminals have 4 mm sockets. The bridge measures 1130 × 80 × 50 mm, and JaincoLab supplies it with a jockey.

Experiments with the slide-wire Wheatstone bridge
In the laboratory the Wheatstone bridge is used to find an unknown resistance: students slide the jockey along the constantan wire until the galvanometer shows no deflection, read the two balancing lengths from the metre scale and apply their ratio to a known resistance; the same set-up gives resistivity and resistance-temperature results.
- Determining an unknown resistance by the balance-point method
- Finding the resistivity of the material of a given wire
- Verifying the laws of combination of resistances in series and parallel
- Measuring the resistance of a coil or platinum resistance thermometer at different temperatures
- Senior-secondary (Class 12) and B.Sc current electricity practicals
