distributed, every 10 metres of line will absorb a certain percentage
of the power put into it. Obviously, a line made of a very thin wire, of
comparatively high resistance, will cause greater loss than one made
of low-resistance wire. So, too, will a pair separated by poor
insulating material (Sec. 8.15). Although the loss due to resistance is
an important property of a line, it is generally allowable to neglect
the resistance itself in calculations such as we have just been making.

The next thing to consider is how to make the feeder fit the load, so
as to fulfil the necessary condition, yj(L/C) = R.
