A conductor-carries a current of 50 muA If the area of cross-section of the conductor is 50 mm^(2) , then value of the current density in Am^-2

Current Density In Conductors

A cylinder conductor AB of non uniform area of cross-section carries a current of 5A. The radius of the conductor at one end A is 0.5 cm.The current density at the other end of the conductor is half of the value at A. The radius of the conductor at the end B is nearly
