Product Code : SCL-EELE-12180
Indian Lab Suppliers supplies the De-Sauty Bridge (Product ID: 12180) as part of its electronics engineering lab equipment range. It is a board for comparing the capacitances of two capacitors with a De Sauty bridge.
Quick Answer
Two single-dial decade resistance boxes, each 0–1 kΩ in 100 Ω steps, form two arms of the bridge, and two single-dial decade capacitors, each 0–1 µF in 0.1 µF steps, form the other two. A high-impedance headphone is used to find the null. At balance C1/C2 = R2/R1, so the unknown capacitance is found from the two resistance settings. A separate bridge oscillator is needed to drive the bridge; the board has no mains supply of its own.
