WebA meter bridge is used to calculate the resistance of the wire and then the resistivity of the material of the wire. The formula for resistance is: X = R× l/ (100-l) The formula for the resistivity of the material: ρ = πr 2 X/L. Minimum four readings should be taken for the calculation of both the resistance of the wire and for the diameter ... WebIn a meter bridge experiment, null point is obtained at \( 20 \mathrm{~cm} \) from one end of the wire when resistance \( X \) is balanced against another re...

To Verify The Laws Of Combination Of Resistances Using A Metre Bridge
WebMar 24, 2024 · As the meter bridge wire is uniform, and as the resistance is proportional to the length, instead of ratio of resistances ratio of lengths of wire are taken. Knowing R and L, x the unknown resistance is calculated. The experiment is repeated with different values of R and the balancing lengths are determined. The reading are tabulated. WebMar 16, 2024 · Hint:A metre bridge, also known as a sliding wire bridge, is a device that works on the Wheatstone bridge idea. It's used to figure out a conductor's unknown resistance. The experiment below shows how to use a metre bridge to estimate the resistance of a specific wire and the resistivity of its substance. Complete step by step … A meter bridge works on the principle of a Wheatstone bridge.
