In a wheatstone bridge three resistance
WebThe principle of the circuit is that if three resistances are known, and the current in the cross branch is zero, the fourth resistance can be calculated. The measurement can be made very accurately since zero current can be detected with extremely high accuracy using a sufficiently sensitive galvanometer. WebA Wheatstone bridge circuit consists of four arms, of which two arms consist of known resistances while the other two arms consist of an unknown resistance and a variable resistance. The circuit also consists …

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) Webcircuit. Even if the Wheatstone bridge is initially balanced resistively so that R 1/R 4 = R 2/R 3, this will no longer be true, in general, when one or more of the strain gages in the bridge arms are strained. Consequently, the Wheatstone bridge is ordinarily operated in a resistively unbalanced state. In this mode of operation, resistance ...
WebWheatstone bridge can be used to determine the value of an unknown resistance in the arrangement of four resistances among which three are known resistances. It was invented by British physicist Charles Wheatstone in 1843.
