What are a few of the differences between resistance and resistivity?
Answer:
The resistance R of wire depends on both the size and shape of the wire and on the resistivity a physical quantity whose value characterizes the material of which the wire is made.
Where l is the length of the wire and A is the cross sectional are of the wire.
