Answer:
it depends upon the conductivity of wire area of cross section, length of wire
Explanation:
more area of cross section ∝ less resistance
more conductivity ∝ less resistance
more length ∝ more resistance
in mathematical form ;
area of cross section ∝ 1 / resistance
conductivity ∝ 1 / resistance
length ∝ resistance
merge it all !!!
resistance = length X R / area of cross section X conductivity
where R is a constant
