In a meter bridge the null point
WebJan 2, 2024 · To Find: Position of null point = l = ? Solution: Let l be the distance of the null point from the left end. For balanced metre bridge ∴ 10/ (80/9) = l / (100 – l) ∴ 9/8 = l / (100 – l) ∴ 9 (100 – l )= 8 l ∴ 900 – 9 l = 8 l ∴ 17 l = 900 ∴ l = 900/17 = 52.94 cm Ans: The null point is at 52.94 cm on the wire from the left end. Example – 02: WebJun 8, 2024 · A resistance R is to be measured using a meter bridge, a student chooses the standard resistance S to be 100 Ω He finds the null point at l1 = 2.9 cm. He is told to attempt to improve the accuracy. Which of the following is a useful way? (a) He should measure l1, more accurately (b) He should change S to 1000 Ω and repeat the experiment

WebIn a meter bridge circuit, resistance in the left hand gap is 2Ω and an unknown resistance X is in the right hand gap as shown in Figure. The null point is found to be 40 cm from the left end of the wire. What resistance should be connected to X so that the new null point is 50 cm from the left end of the wire? Medium View solution > WebThis is the null point as represented by the point ‘\ (B\)’ in the diagram. Obtain the length of the null point using the meter scale attached along the wire. This is the ‘balancing length’ of the meter bridge. Let the distance between points \ (A\) and \ (B\) be ‘\ (l_1\)’.
