Consider a thin square sheet of side L and thickness t, 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
The area of each opposite face `A= Lxx t` for a sqaure plate length of each side = L
`therefore R =(rho L)/(A)=(rho L)/(Lt)= (rho)/(t)`
Thus R does not depend upon L
