Understanding Current Flow in Wheatstone Bridge: Diagram and Explanation

[pavel987]

In wheatstone bridge , if B an D are two points and if potential difference of B is greater than D,How current will flow?
If possible you can draw a diagram and explain me how current will flow(send pdf or doc).It will be very helpful for me.

First, it does not make sense to talk about the potential difference at one point. One may only define the potential at one point and the potential difference between points. If you mean that the potential at B is greater than at D, then positive charges released at rest at B would move toward B and vice versa for negative charges. Since the current is defined in terms of the flow of positive charges (even though it's actually electrons which are moving), the current flows from points of higher potential to points of lower potential.

It also helps to know what resistors you are labelling as B and D.

1. Please read the posting rules for this forum - we can not help you with coursework unless you show us what effort you've made.

2. The question is vague and incomplete. At least draw or describe the bridge and indicate where the points lie.

3. All homework discussion is to be had in the forums, so that future questions along these same lines can be directed to this thread.
