the length of a wire is tripled and the area of cross-section is doubled. How does it effect the resistivity of the wire.Give reason.

it will not affect resistivity at all because resistivity is
constant and hence, doesn't depends upon the
length and area of cross section. hence, no change
in resistivity will take place.
