I'm going to use a slip ring connector (such as this one) to power 6 servos on the other end of a rotary. This slip ring is rated for 2A of current per wire/ring.
If the 6 servos share a common +6v and ground, they will easily exceed 2A current draw. My naive understanding of conductance tells me that if I use two of the wires for +6v instead of one (and two for ground), I can effectively double the amount of current available to the servos because the first wire/ring (the one with initial least resistance) will heat up as it approaches the maximum rated current, becoming more resistant than the alternate wire/ring.
Am I wrong to assume that this setup would allow me to provide more than 2A through the slip ring?
