Answer:
(a)
(b)
Explanation:
(a) The surface current density of a conductor is the current flowing per unit length of the conductor.
Considering a wire, the current is uniformly distributed over the circumferenece of the wire.
The radius of the wire = a
The surface current density
(b) The current density is inversely proportional
......(1)
k is the constant of proportionality
........(2)
substituting (1) into (2)
