Answer / appar

in this situation current is flowing only the outer most
part of the conductor,that time current innerpart will get
heat it will act as a resistance and cross section of the
conductor will be less.

as my frriend says,
the cross section will not be reduced in phisycally,
however the useful or wsable cross section is reduced while
the conductor is the same,where the current will be flowing
in the outer more than the inner

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
