2.1 Theory A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. 0000020216 00000 n When the bridge is balanced then on interchanâ¦ Using these laws, deduce the condition for balance in a Wheatstone bridge. The Wheatstone bridge is in thebalanced bridge condition when the output voltage (V OUT) between terminals A and B is equal to zero. Here R1, R2are known resistances, R3is variable (adjustable) and R2 is the one which needs to be measured. 0000020494 00000 n Ìþ6çØe°i1 Rh3äÍLasÁ*$cV5XÜL¾Áäk0¹L¾pÁfÐw-ÆAAÈì%@ ¾® It is possible to eliminate the temperature effect with either two (half-bridge) or four active sensor elements (full-bridge) connected to form a Wheatstone bridge circuit [4] - [6]. 0000001288 00000 n 0000014082 00000 n notation of Wheatstone, and b) is another notation that is usually easier to understand by a person without a background in electrical or electronic engineering. Wheatstone bridge is designed in a bridge type structure having four resistances, three known and one unknown. Forms of Wheatstone Bridge Circuits. The formula for a wheatstone bridge is below, it can be used to rescale the wheatstone bridge for different ranges gotten from the pdf table attached. A resistance bridge is especially useful when a very accurate measurement of a resistanceis required.

View Lab Report - PHY1002 Wheatstone bridge.pdf from PHY 1002 at Bahcesehir University. Definition: Wheatstone bridge is a type of dc bridge that is used for the measurement of unknown resistance.It is a series-parallel combination of 4 resistances that provides zero difference voltage at the balanced condition.
