The answer to both questions depends on the answer to two other
questions -- 1) how much current is drawn in these two circuits when
they are in use, and 2) at how low a voltage will they function
adequately? Both of these answers SHOULD be on the manufacturer's
data sheet. From there you do Ohm's law, using the wire resistance
data from the Handbook (don't forget to double the length of the run
to get the total resistance).
