WebNov 2, 2024 · A resistance of 2 Ω 2 Ω is connected across one gap of a meter-bridge (the length of the wire is 100 cm) and an unknown resistance, greater than 2 Ω 2 Ω, is connected across the other gap. When the resistances are interchanged, the balance point shifts by 20 cm. Neglecting any corrections, the unknown resistance is, 3 Ω 3 Ω. 4 Ω 4 Ω. 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
