Wheatstone Bridge Two Gap
Product Code : JA-EE-7587
The Wheatstone Bridge Two Gap (SKU JA-EE-7587) is a two gap metre bridge: a known resistance goes in one gap, the resistance under test in the other, and the balance point on the wire gives the unknown value. Its 24 SWG constantan wire runs along the top of a metre scale in mm and cm, the heavily plated brass strips sit on a polished hardwood base, and the terminals have 4 mm sockets. JaincoLab supplies this two gap meter bridge with a jockey for school and college physics laboratories.
Specifications
The two gap bridge carries a 24 SWG constantan wire stretched along a metre scale in mm and cm, broad heavily plated brass strips mounted on a polished hardwood base and 4 mm socket terminals; it measures 1130 × 80 × 50 mm and comes with a jockey.

Practicals with the two gap meter bridge
With a resistance box in one gap and the test resistance in the other, students move the jockey along the constantan wire to the null point and use the two balancing lengths to calculate the unknown resistance; interchanging the two resistances and averaging the results reduces end errors.
- Resistance of a given wire and the resistivity of its material
- Series and parallel combinations of resistances
- Comparison of two resistances by interchanging them between the gaps
- Variation of the resistance of a coil with temperature
- Class 12 physics practical examinations and first-year college current electricity labs
