Answer / digambar

The loop gain is equal to unity in absolute magnitude, that
is, |\beta A| = 1\,;
A=gain of the amplifying element in the circuit;
beta=transfer function of the feedback path.

Answer / sanchayan pandit

When the product of the gain of the amplifier without
feedback(A)and feedback factor(B)IS equal to unity,i.e AB=1,
then it is called bark housen cirterian...is the condition
of osillator.

potentiometer : it is null or deflecting instrument
