    1) What is the current density of aluminium compared to copper conductors?
    2) What is resistances of aluminium compared to copper conductors in terms of Rt=R0*(1+α*Δt) where R0 is resistance at t = 20 degree Celsius, α = coefficient of aluminium or copper conductor and Δt = diference in temperature?
