Assume current flows in a cylindrical conductor in such a way that the current density increases linearly with radius, from zero at the center to 1.0 A/m^2 at the surface of the conductor. If the conductor has a cross sectional area of 1.0 m^2, what can you say about the current in this conductor? The current is more than 1.0 A. The current is less than 1.0 A. The current is 1.0 A. Any of these choices might be correct.
