MCQ

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

A
$240$
B
$24$
C
$48$
✓
$2400$

✓

Answer

Correct option: D.

$2400$

d
$\frac{ S }{30}=\frac{5.6 \times 10^{3}}{70}$

$S =\frac{3}{7} \times 5.6 \times 10^{3}=2400$
