Wein’s Bridge Frequency Measurement
This bridge has been designed to calculate the unknown value of frequency of Bridge Oscillator.
Detector:For detecting small AC signals in the output, Null Detector is in-built with digital display (optional - sometime Digital null detector is replaced by small speaker).
Circuit Diagram:The circuit layout on the board is quite spread out to facilitate convenient working & clear understanding. 4mm socket are provided for making connection.
C1, C2 :Decade dial of 0.1mfd.
R3 :Ratio Dial of 1, 10, 100 & 1000
R4 :Ratio Dial of 2, 20, 200 & 2000
R1 R2 :Are mechanically coupled x10, x100, x1000 ohms.
