Hey all, I've been thinking of a couple scenarios that involve thin wires (ones that have their diameter in the order of 1 mm). Suppose a gold wire with length L and diameter D is suspended straight in room temperature air and connected to some voltage V. Thus, a current will pass through the wire. What must one consider when trying to analyze the wire? For example, would the (relatively) thin wire heat up significantly? Or, would enough of that heat be dissipated into the surrounding air so that any temperature effects can be ignored? Could the wire curl up? deform? And are there any other effects I haven't considered? I'm just trying to learn more about the nature of thin gold wires. Any input from the community will be greatly appreciated.
