How to find area using resistance formula if required information is available Share with your friends Share 0 Raghav Kumar answered this Dear student, For a conductor materal; if its resistivity is given as ρ, length of the conductor is given as l, and resistance of the conductor is known as RLet the area of cross-section of the conductor be A.Then relation between these quantities is given as,R=ρlA⇒A=ρlRIn this way ,area of cross-section of the material of the conductor can be found if rest of the three quantities are known.
