In a meter bridge experiment resistance box
WebThe meter bridge uses the same principle as the Wheatstone Bridge. It is used to find the unknown Resistance of the Material. The meter bridge consists of a wire of 100 cm, a scale, one unknown Resistor, one known … 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.
