( S /30)=(5.6 × 103/70) S =(3/7) × 5.6 × 103=2400

Q. In meter bridge experiment for measuring unknown resistance ' $S$ ', the null point is obtained at a distance $30 c m$ from the left side as shown at point $D$ . If $R$ is $5.6 k Ω$ , then the value of unknown resistance ' $S$ ' will be _____ $Ω$

$\frac{S}{30} = \frac{5.6 \times 1 0 ^{3}}{70}$
$S = \frac{3}{7} \times 5.6 \times 1 0^{3} = 2400$
