Question

A De Sauty's (Modified) bridge is used to measure the capacitance of a sample of sheet chage at 2kHz. At balance, arm ab is a resistor R1=300Ω in series with a capacitor C1=0.21uFuF; arm bc is R3=600Ω; arm cd is R4=200Ω and arm da is a resistor R2=1kΩ in series with a unknown capacitor C2. Capacitor C1 has internal resistance r1=60.2Ω. Calculate the effective impedence of the unknown capacitor under test conditions.​
