Column I gives physical quantities based on a situation in which an ideal cell of emf V is connected across a cylindrical rod of uniform cross-section area and conductivity (sigma) as shown in figure E, J, phi and I are electric field at, current density through, electric flux through and current through shaded cross section repectively as shown in figure. Physical quantities in column-II are equal to those in column i Match the expression in Column I with the statement in Column II
