In an aluminium (Al) bar of square cross section
In an aluminium (Al) bar of square cross section, a square hole is drilled and is filled with iron (Fe) as shown in the figure. The electrical resistivities of Al and Fe are 2.7 × (10^−8) Ω m and 1.0 × ( 10^−7 )Ωm, respectively. The electrical resistance between the two faces P and Q of the composite bar is
