Presumably by "join 2 lengths" you mean to connect two lengths in
parallel.

If the loss factor L is the loss in one length of the cable, won't the
loss in two parallel lengths be Plost=Pin/2*L+Pin/2*L, so Plost/Pin=L?


Hi Owen,

Hmm, each time I look at these equations, something is missing, but I
don't know what (probably because it is missing).

Simply put, two lines in parallel lose as much power as one line.
Nothing to be gained in that regard.
