Aluminum has a resistivity varying from 2.65 to 2.82 × 10−8 Ω m.The resistivity of copper is generally given as: 1.72 x 10-8 Ω.m.So, since resistivity of aluminium is higher than that of copper, so Power dissipated will be greater than P. this is because rest of the factors (l, A and i) are constant.
