About this document
Construction and Theory of Wheatstone Bridge by prarthana is a document available to read on EtoBox.
This document discusses the construction and theory behind a Wheatstone bridge circuit. The circuit consists of four resistances connected in four arms, with a source connected between points AC and a galvanometer/null detector connected between points BD. When the balance point is reached, no current flows through the galvanometer. The ratio of the resistances in the ratio arms R1/R2 is equal to the ratio of the resistances in the other two arms R3/R4, allowing the unknown resistance R4 to be calculated if
