In example 1 series you have 2 12 inch leads out of the pack.
In example 2 parallel you use all the leads to connect them together and the
12 inch leads out of the pack are missing, They would add .001 ohm each if
the same size wire which is a second 40 watts.
View with a fixed-width font like Courier. Ignore the dots; they just
trick Microsoft into not deleting all the extra spaces.
Example 1 (series), four 12" pieces of wire (the / and \):

Identical wire sizes, wire lengths, and wire resistive losses,
regardless of whether wired for low voltage or high voltage.
The purpose is not to show that one way or another is always "best". It
ain't that easy! The point of these examples is that you have to THINK
about how things are wired, and not just fall for conventional wisdom
that is often inappropriate or even wrong.
