Hi everyone,
I'm new to this field. When I wished to make a bridge circuit output linear I found a circuit, I have attached circuit in the attachments. In circuit description it is mentioned that irrespective of the resistance change in the branch, current would still remain same (Ib/2). Here my doubt is how come even resistance is changing branch current is same in the both the branches. Please clarify my doubt someone in the forum. Thanks in advance.
