plz help frnds
A conductor of length l has a non uniform cross section . The resistivity of the material is Ï.
Assume b-a<<l ,find the resistance of the conductor across its end

R=Ï*(length of conductor along which current flows)
(area of cross-section perpendicular to which current flows)
as we know cross section area of elliptic section is πab
=>R= Ïl
Ï€ab
