In a meter bridge as shown in the figure, it is given that resistance $Y = 12.5 Ω$ and that the balance is obtained at a distance $39.5 cm$ 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 $l_{2}$ ?

Question

In a meter bridge as shown in the figure, it is given that resistance

Y = 12.5 Ω

and that the balance is obtained at a distance

39.5 cm

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 )&#215;&#8203; 39.5 = x &#215; 100 - 39.5 , x = 12.5 &#215; 39.5 60.5 = 8.16 &#160; &#937; . When x &#160;and&#160; y are interchanged l 1 and ( 100 &#8722; l 1 ) will also interchange, l 2 = 60. 5 &#160; cm .
