The figure below represents a section of a circular conductor of nonuniform diameter carrying a current of I = 5.10 A. The radius of cross-section A is r = 0.310 cm. Az A (a) What is the magnitude of the current density across A? A/m The radius r at A2 is larger than the radius r at A. (b) Is the current at A2 larger, smaller, or the same? The current is larger. The current is smaller. The current is the same. (c) Is the current density at A larger, smaller, or the same? The current density is larger. The current density is smaller. The current density is the same. Assume A = 34 (d) Specify the radius at A mm (e) Specify the current at A A (f) Specify the current density at A- A/m
