As the voltage transmission increases, the volume of conductor
increase
does not change
decrease
increase
proportionally
decrease
As we know
that volume of conductor in a; transmission line is inversely proportional to
square of voltage.
Volume of conductor 
If the
voltage of transmission line increases then volume of conductor decreases.
Hence, the
correct option is (C).
