# Anisotropic Resistivity

Electricity and Magnetism Level 5

A material has anisotropic resistivity such that its resistivity in one direction say along the x axis has maximum value $$\rho_{max}$$ and minimum value $$\rho_{min}=\frac{2\rho_{max}}{5}$$ along other axes which are perpendicular to the x-axis from a specimen of such a material is cut a strip ABCD of length l=9cm and width b=1cm . The x-axis passes through the strip making an angle $$\theta$$ with the edge AB as shown in the figure. If between the faces AD and BC a constant potential 196 is applied. The potential difference between points P and Q of the midpoints of AB and CD respectively that you will expect is maximum when $$(\theta=1+x)$$ $$** radian**$$

find $$[100x]$$ where [.] Is greatest integer function
