If a resistance of 12 Ω is connected in parallel with S, the null point occurs at 50.0cm from A. …
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
