MCQ

A rectangular parallelopiped is measured as $1\,cm \times 1\,cm \times 100\,cm$. If its specific resistance is $3 \times 10^{-7}\,\Omega\,m$, then the resistance between its two opposite rectangular faces will be $..........x^{-7} \Omega$.

A
$2$
B
$1$
✓
$3$
D
$4$

✓

Answer

Correct option: C.

$3$

c
$R =\rho \frac{\ell}{ A }=\frac{3 \times 10^{-7} \times\left(1 \times 10^{-2}\right)}{100 \times 1 \times 10^{-4}}$

$=3 \times 10^{-7} \Omega$
