In a meter bridge experiment resistance box

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 ...
