The length of pieces of wire of the same diameter,each piece having a resistance of one ohm,will depend on the metal of which they are made.Again,for the same diameter,a wire of low resistance will be longer than one of high resistance.A copper wire will be longer than one of iron,or lead,or nickel,for its resistance is very low,and not much energy is needed to overcome it.

数个导线拥有相同的直径与一欧姆的电阻,他们的长度是取决于每个制作导线的材质.
.Again,for the same diameter,a wire of low resistance will be longer than one of high resistance
再来,拥有者相同的直径,低电阻的电线会比高电阻的导线还长.
A copper wire will be longer than one of iron,or lead,or nickel,for its resistance is very low,and not much energy is needed to overcome it.
一个铜做的导线会比铁,铅或是镍做的导线还来得长,因为铜的电阻很小,只需要少量的电能就能通过导线.
希望能帮得上忙哦:)
