Answer Posted / c.rajesh
generally current carrying is depends on resistance of
conducting elements but we now pure conductors are not exists
so internal resistance is considered now calculation is made
as resistance directly proportional to area of conducting
element R=l*a/s
here l=length of conductor
a = area
s = specific conductance
