1. The problem statement, all variables and given/known data A section of a circular conductor of non uniform diameter carrying a current of 5.00 A. The radius of the cross-section A1 is 0.400cm.(a) What is the magnitude of the current density across A1?(b) The radius at A2 is larger than the radius at A1. Is the current at A2 larger, smaller, or the same? Is the current density larger, smaller, or the same? Assume one of these two quantities is different at A2 by a factor of 4 from its value at A1. Specify the current, current density, and radius at A2. 2. Relevant equations J=I/A 3. The attempt at a solution J=I/A= 5.00A/pi(.004)^2=99,472.8 A m^2 Is this right so far? I'm not sure since it's nonuniform. If it is then how do you find the current for A2? and if it's not then what do I need to do?
