Consider the Maxwell bridge shown in Figure 8–18. Suppose we know that the unknown impedance is an unknown capacitor CX in parallel with an unknown resistance RX. Let Z1 be a resistance R1 in series with an inductance L1. Let Z2 be a resistance R2 and Z3 be a resistance R3. Find the relationships that will allow the bridge to be balanced.
