A conductor is made of an isotropic material and has shape of a truncated cone. A battery of constant emf is connected across it in figure. If at a section at a distance \( X \) from left the electric field intensity, potential and the rate of generation of heat per unit length are \( E, V \) and \( H \) respectively, which of the following graphs is/are correct?
(a)
(c)
