Theory: A Carey foster bridge is principally same as a meter bridge, which consists of four resistances P, Q, R and X that are connected to each other as shown in figure 1. Figure 1: Wheatstone's bridge WebIn the box form of bridge, used in Experiment 9, R2 consists of a 4-dial resistance box with one dial for each of thousands, hundreds, tens and units of ohms. R3 and R4 are combined into the multiplier dial. In the slide wire form of bridge, used in this experiment, R2 is a plug resistance box. R3 and R4 together make up a one-meter length of ...
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 ...
