De Sauty's Bridge This bridge compares two capacitances and it is the simplest bridge. Figure (a) shows the schematic diagram of the De Sauty's bridge.
figure (a) Let C1 is capacitor whose capacitance to be measured, C2 is standard capacitor, and R3, R4are non-inductive standard resistors To obtain the balance either R3 or R4 can be varied. The bridge is very simple. This simplicity is nullified by the fact that there is dielectric loss-free capacitors. The air capacitors can be compared with this method. | |
