Question

In a meter bridge as shown in the figure, it is given that resistance $Y = 12.5Ω$ and that the balance is obtained at a distance $39.5 c m$ from end $A$ (by jockey $J$ ). After interchanging the resistances $X$ and $Y$ a new balance point is found at a distance $l_{2}$ from end $A$ . What are the values of $X$ (in $Ω$ ) and $l_{2}$ ?

For a balanced meter bridge, ( y ) × ​39.5 = x × ( 100 − 39.5 ) , x = 60.5 12.5 × 39.5 ​ = 8.16Ω . When x an d y are interchanged l 1 ​ and ( 100 − l 1 ​ ) will also interchange, l 2 ​ = 60.5 c m .
