Question

How to find the equivalent resistance of a balanced wheatstone bridge?

Answer 1

Answer:

The Wheatstone Bridge was originally developed by Charles Wheatstone to measure unknown resistance values and as a means of calibrating measuring instruments, voltmeters, ammeters, etc, by the use of a long resistive slide wire.

Although today digital multimeters provide the simplest way to measure a resistance. The Wheatstone Bridge can still be used to measure very low values of resistances down in the milli-Ohms range.

The Wheatstone bridge (or r

Answer 2

Hey there,
I’m Siddhant.
Let me answer your question.

So, the equivalent circuit reduces to two parallel voltage dividers. - 11.11 = 2.64 V. determining resistance between points A and B. For an unbalanced Wheatstone Bridge, you can use something called the voltage node method.

Hope this answers your question.
