Consider a thin square sheet of side L and thicknest, made of a material of resistivity `rho`. The resistance between two opposite faces, shown by the shaded areas in the figure is

A

directly proportional to `L`

B

directly proportional to `t`

C

independent of `L`

D

independent of `t`

Text Solution

Verified by Experts

The correct Answer is:
C
`R=(rho(L))/(A) = (rhoL)/(tL)=rho/t`
i.e `R` is independent of `L`.
Hence the correct option is c.
