What Diameter Must a copper wire have if its resistance.?
What diameter must a copper wire have if its resistance is to be the same as that of an equal Length of Aluminum wire with diameter 3.78 mm?
_______
Resistance R=pL/A=pL/pi(d/2)^2
AS resistance of Aluminium wire is equal to resistance of copper wire,
pa/(da)^2 = pc/(dc)^2
dc = da sq rt [ pc/pa]
dc = 3.78*10^-3 sq rt [1.68*10^-8/2.82*10^-8]
dc = 3.78 *10^-3sq rt [0.59574]
dc = 3.78 *10^-3*0.7718
dc =2.92*10^-3 m
Diameter of copper wire =2.92 mm
