Two wires of equal length, one of aluminium and the other of copper have the same resistance. Which of the two wires is lighter ? Hence explain why aluminium wires are prefered for overhead power cables ? Given `rho Al=2.63xx10^(-8) Omega m rho Cu=0.72xx10^(-8) Omega m` , relative density of Al=2.7 and that of Cu =8.9.

Two wires of equal length, one of aluminium and the other of copper have the same resistance. Which of the two wires is lighter ? Hence explain why aluminium wires are preferred for overhead power cables. (rho_(Al) = 2.63 xx 10^(-8) Omega m , rho_(Cu) = 1.72 xx 10^(-8) Omega m, Relative density of Al = 2.7 , of Cu = 8.9 )

Two wires of equal length, one of aluminium and the other of copper, have the same resistance. Which of the two wires is lighter ? Hence, explain why aluminium wires are preferred for overhead power cables. (rho _(Al)=2.63xx10^(-8)Omega -m ,P_(Cu)=1.72xx10^(-8)Omega -m , relative density of Al=2.7,of cu =8.9)

Two wires of equal length, one of aluminium an the other of copper have the same resistance. Which of the two wires is lighter ?
