WebDec 21, 2016 · A Wheatstone bridge is used to measure tiny changes in R using a fixed V which gives a fairly constant I. When R changes 50%, I is no longer constant. So this bridge is no longer linear or balanced with a wide spread. This "Wheatstone bridge" does not pass the criteria of a small change so it is not linear as Wheatstone intended when balanced.
WebIn a Wheatstone's bridge, three resistances P,Q and R are connected in three arms and the fourth arm is formed by two resistances S 1 and S 2 connected in parallel. The condition for the bridge to be balanced will be : A QP= S 1+S 22R B QP= S 1S 2R(S 1+S 2) C QP= 2S 1S 2R(S 1+S 2) D QP= S 1+S 2R Hard Solution Verified by Toppr Correct option is B) WebMay 13, 2024 · If we consider each resistor separately, each resistor has its own current (i1, i2, i3, and i4), resistance (R1, R2, R3, and R4), and voltage (V1, V2, V3, and V4), which are related to each other through Ohm's law. In …
