A cylindrical, non-ohmic, uniform conductor is placed in a uniform electric field that points from bottom to top along the axis of the conductor, which is aligned with the z-axis. Which of the following statements is correct (select all that apply)? The current density is proportional to r (the radial distance from the axis) O The current density is proportional to the cube of the conductor's radius O The current density is proportional to the conductivity O The current density is inversely proportional to the cross-sectional area of the conductor
