Can a copper wire and an aluminum wire of the same length have the same resistance? Explain.
Step 1 of 1
The resistance of a wire is:
- resistivity of the wire
L - length of the wire
A - area of cross section of the wire
We see that resistance of the wire depends from its length but also from the area of cross section.
If the ratio of resistivity to area is the same for both copper wire and aluminium wire, then the resistances will be the same.
