1you mean that at a dist x radius = r+x2 ??
find the resistance of a wire of length L
which has a radius of r on one end and R on the other
The radius changes uniformly with length
And the resistivity is Ï
Philip points out that this is in HCV.. So I have changed the question a bit...
the radius varies as the square of the distance from the side where Radius is "r"

62hmm.. okie.. i din know it is there..
may be then we can change it a bit.. To the following...
the radius varies as the square of the distance from the side where Radius is "r"
1ok i got
L
L2p/π ∫ dx/(L2r+x2(R-r))2
0
and i dont see any short method and also i don't want to use trigonometry in this now [2]
