In a meter bridge, the length of the wire is 100 cm. At what position will the balance point be obtained if the two resistances are in the ratio 1:3?

Verified by Experts

Here, `X/R = 1/3`. Let the balance point be obtianed at length l of bridge wire from the end having resistance X. Then
`X/R = l/((100-l)) or 1/3 or l/((100-l)) or l = 25 cm`.
