(b) Figure Q3(b) shows a simple capacitance bridge, also known as De Sauty bridge circuit and is used to measure an unknown capacitance. It consists of two purely capacitive impedances; standard capacitance (Zı) and unknown capacitance (Zx), and two purely resistive impedances; Z3 and Z4. (i) Based on a balanced bridge in Figure Q3(b), derive the formula for the unknown capacitance (Cx). (ii) The bridge has a standard capacitance of 0.1 µF and adjustable range of R3 and R4 from 1 kN to 200 kN. Analyze the minimum and maximum values of capacitance that can be measured using the bridge.

Wheatstone Bridge Method

A Wheatstone bridge is a circuit used to measure unknown resistance by measuring the ratios of the two branches of the circuit such that each branch has two resistance and out of four resistance one is unknown. The two branches are joined in between with the help of galvanometer which is used to determine the direction of the current. The main advantage of this circuit is that it can provide the most accurate measurement (different from a simple voltage separator).
