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.
