Answer:
The Wheatstone bridge is a circuit which is used to measure accurately an unknown resistance.
PRINCIPLE: Wheatstone bridge principle states that when the bridge is balanced, the product of the resistance of the opposite arms are equal.
The files that I had attached in which I had derived Wheatstone bridge equation using Kirchhoff law is useful to you.

Its Principal theory and Proof
The Wheatstone bridge is the interconnection of four resistances forming a bridge. The four resistance in circuit are referred as arms of bridge. The bridge is used for finding the value of an unknown resistance connected with two known resistor, one variable resistor and a galvanometer.
