how does it work?? i am really too confused and can't understand its idea.

can anyone help??

It is a modification of Maxwell’s L - C
bridge. In this bridge, double balance is obtained by the variation of resistances only, the
value of capacitance being fixed.
Anderson’s bridge is the most accurate bridge used for the measurement
of self – inductance over a wide range of values, from a few micro-Henries to several
Henries. In this method the unknown self-inductance is measured in terms of known
capacitance and resistances.
go in your EIM lab and take experiment manual in place of DETECTOR you can use HEAD PHONE and then measure its self-inductance...

i give you a brief explanation ....

the inductance of given coil L = C [ ( R1+ R2 ) R5 + R2R4 ] mH (it is formula to obtain unknown inductive resistance )

Where C = Capacity of the standard capacitor ( µ F )
R2,R3,R4 = Known, fixed and non – inductive resistances (KΩ)
R1, R5 = Variable resistances ( KΩ )
see diagram in your book..
