This
bridge is used to measure the unknown value of capacitance. The instrument has
following in built parts
fitted in teak wood 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.
Unknown value: Five unknown values are provided
on the board selected by a Rotary switch.
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.
R1, R2 : Two decade dial of x10 & x100 ohms.
R1, R2 : Decade dial of x0.1mfd.
