Circuit Diagram:

1) Connect all the components and the air cored coil as shown in the figure.
2) Set the product of R2R3 at a convenient value and obtain the balance by varying R1 and C1.
3) Decide the ranges for R1 and C1 through which they can varied wihout bringing database at noise C.R.O.
4) Repeat the procedure with different values of the product R2R3 and decide upon readings that permit maximum accuracy for the
measurement.
