In a meter bridge the null point is found
WebIn the meterbridge experimental set up, shown in the figure, the null point ‘D’ is obtained at a distance of 40 cm from end A of the meterbridge wire. If a resistance of 10Ω is connected in series with R 1, null point is obtained at AD = 60 cm. Calculate the values of R 1 and R 2. WebIn a meter bridge experiment the null deflection is obtained at a length of 25cm. When a standard resistance of 5 ohm is employed. The value of resistance in the left gap is A 2 Ω B 1.66 Ω C 4 Ω D 1.2 Ω Medium Solution Verified by Toppr Correct option is B) ⇒ 5R= 100−2525 (standard result) 5R= 7525 R= 35=1.66Ω Video Explanation
