The same thick copper wire and copper strip. Is that conductive well?
For a higher frequency alternating current, the conductor of the same material, in the case of cross-sectional area, conductor conductivity, multi strand line is better than single strand;
For DC, conductive material is the same length as the resistivity, section size, the conductor made the same material, the resistance value is the same, the conductor length, the smaller the cross-sectional area, the greater the resistance value; if the resistivity of the materials are not the same, the resistance rate of small resistance. A good conductivity, all kinds of copper in substantially less resistivity;
Copper wires and copper bars are simply different in terms of their length and length.
The same copper, depending on the cross-sectional area of the conductor, the greater the area, the better the conductivity.
