In a meter bridge the null point
WebDec 4, 2015 · 24.In a meter bridge, the null point is found at a distance of l1 cm from A. If a resistance of X is connected in parallel with S, then null point occurs at a distance l2 cm from A Obtain the formula for X in terms of l1,l2 and S. Ans. Ans. Ans . (i) 27. (i) State the principle of working of a meter bridge. WebThe null point is at 40 cm mark. So, it divides the resistance of the wire into two segments. One of length 40cm and other of length 60 cm as the total; length of the meter bridge wire is 100cm. So, the ratio of the resistance will be same as the ratio of the lengths R 2R 1= 6040= 32 . (i) R 2R 1+10=1⇒R 1+10=R 2 .. (ii) 32R 2+10=R 2
