In Fig.01, the variable cross section of a circular conductor with a non-uniform diameter that conducts a current of intensity I=5 A is shown. The radius of the cross section A1 is R1=0.4 cm. If the current density through A2 is one quarter of the value through A1, what is the radius of the conductor in A2? A2
