Measurement of Self-Inductance by Maxwell's Bridge

Procedure

Fig 1: Circuit Diagram for experimental set-up of Maxwell's bridge

1. Connect all the components and the air cored coil as shown in the figure.
2. Set the product of R₂ R₃ 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 without bringing database at noise C.R.O.
4. Repeat the procedure with different values of the product R₂ R₃ and decide upon readings that permit maximum accuracy for the measurement.
