Question

Hola ... good. evening ......write construction and working, principle of Wheatstone bridge...​

Answer 1

Answer:

Hii.. good evening Vicky bro...

Wheatstone is an arrangement of for sister in the form of a bridge used to determine is there one unknown resistor in term of three non resistor

construction:- it consist of four resistor P Q R and S.the unknown resistorvas S oneis are variable resistor and PS are standard resistor.a cell of EMF is connected between the point A and B a galvanometer is fixed B and y a key

principles:- Venky ke is closed and Kelvin Twitter show deflection answer current IG flow through it by the adjusting value are so that the Galvanometer shono direction at the state v and is equal that the weight of stoneridge is at balanced state.

$p \div q = r \div q$

Answer 2

Answer:

The Wheatstone bridge works on theprinciple of null deflection, i.e. the ratio of their resistances are equal, and no current flows through the galvanometer. The bridge is very reliable and gives an accurate result

Principle of Wheatstone bridge experiment. According to the wheatstone bridge principleif the ratio of the two resistance (R1/R3) on the one edge is equal to the ratio of the two resistance (R4/R2) in another edge then there will be no flow of current between the midpoints of the two edges of resistance.
