Consider a thin square sheet of side $L$ and thickness $t$ , made of a material of resistivity $ρ$ . The resistance between left and right extreme in the figure is

Options:

Answer:

Solution:

$R = \frac{ρ ( L )}{A} = \frac{ρ L}{t L} = \frac{ρ}{t}$ ie, $R$ is independent of $L$ . Hence the correct option is (c).
