Well, actually I mean:

the Ampere addresses the current in a conductor, which is usually a wire.

There Ampere does not say, whether the wire is thick or thin, or whether 
or not the current distributes evenly within the wire.

If you have a wire with a current of 1 A, you don't mean the 
distribution of the current within the conductor, but the sum of all 
small partial currents within that wire.
