Maxwell Inductance Bridge

Maxwells Bridge is used to measure the unknown value of Inductance. The instrument has following inbuilt parts fitted in ABS Plastic case.

AC Source :The Bridge consist of sine wave signal of 1KHZ. The Amplitude of AC switch indicating lamp is provided on the bakelite board. Two sockets are provided for the output of AC signals.

Detector :For detecting small AC signals in the output, Null Detector is in-built with digital display.

Circuit Diagram :The circuit layout on the board is quite spread out to facilitate convenient working & clear understanding. 4mm socket are provided for making connections.

Features:

P ---- Three decade resistance dials having value 10, 100W, 10-10W and 10,1W
R ---- Single decade resistance dial having value 10,100W.
L_1----- Fixed standard inductance having value 20 mH
L₂---- unknown inductance.
R1----Continuously variable resistance 0 to 100 ohm for impedance matching in dc arm.

Terminals are provided for external connections to connect unknown inductance.
