Maxwell’s Inductance-Capacitance Bridge

qImage6817a939f0bda51088c5cd50

Maxwell's Inductance-Capacitance Bridge uses a standard capacitor to measure an unknown inductance; it compares the unknown inductance to the known capacitance to determine its value. 

Balance Conditions:

At balance (no current through the detector), the following formulas apply:

\(R_1={R_2R_3\over R_4}\)

The value of the unknown inductance is given by:

\(L_1=R_2R_3C_4\)
