Aim- Measurement of capacitance by De-Sauty’s Bridge.
Apparatus- De-Sauty Bridge set up, Headphones, AC Supply, Wires.
Theory- The De Sauty Bridge consists of four arms, each containing a capacitor and a resistor. The arms are arranged in a diamond configuration, with a voltage source applied across one diagonal. One of the capacitors is the unknown capacitor Cx, while the other three capacitors are known C1, C2 and C3. The bridge is considered balanced when there is no audio output detected across the headphones.
This balance condition is achieved when the impedance of the headphones matches the known impedance or resistance values in the other arms of the bridge.
