Metre bridge experiment pdf

A meter bridge is an electrical apparatus that is used to measuring the unknown resistance of a conductor. It consists of a wire of length one meter. Hence it is called a meter bridge. Question 3: In a meter bridge, there are two unknown resistance R and S. Find the ratio of R and S if the galvanometer shows a null deflection at 20cm from one end? filexlib. The metre bridge, consists of a one metre long wire of uniform cross sectional area, fixed on a wooden block. A scale is attached to the block. Two gaps are formed on it by using thick metal strips in order to make the Wheat stone's bridge. The terminal B between the gaps is used to connect galvanometer and jockey. The meter bridge experiment is used to test the laws of resistance and figure out unknown resistances. Meter Bridge wire is made of copper-nickel alloy (constantan), alloy manganin, and chromium, nickel, and iron alloys (nichrome) as they are resistant to corrosion. In Wheatstone's metre bridge experiment with unknown resistance X in the left gap and 60 Ω resistance in a right gap null point is obtained at l cm from the left end. If the unknown resistance is shunted by equal resistance, what should be the value of resistance in the right gap in order to get the null point at the same point? Solution: Case - I:

It is an instrument which works on the principle of a Wheatstone bridge . A meter bridge is used in finding the unknown resistance of a conductor as that of in a Wheatstone bridge.
For balanced metre bridge. ∴ X/30 = 40 / 60 = 2/3. ∴ X = 20 Ω. Case a) when the resistance in both the gaps are increased by 15 Ω. resistance in left gap = X + 15 = 20 + 15 = 35 Ω, Resistance in right gap = 30 + 15 = 45 Ω. Let l cm be the distance of null point from left end. For balanced metre bridge.
