• Power output varies with temperature.
As pipe temperature increases, power output decreases.
• At high temperatures, the polymer expands, reducing
the number of the conductive paths, and thus reducing
current flow.
• At low temperatures, there are many conductive paths,
allowing current to flow between the conductors.
