Question

# 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

Solution

## The correct option is D independent of LAs $$R= \rho \dfrac{l}{a}$$Therefore $$R=\rho \dfrac{l}{l\times t}=\dfrac{\rho}{t}$$Physics
