A conductor having resistivity `rho` is bent in the shape of a half cylinder as shown in the figure. The inner and outer radii of the cylinder are `a and b` respectively and the height of the cylinder is `h`. A potential difference is applied across the two rectangular faces of the conductor. Calculate the resistance offered by the conductor.

Text Solution
