Quote:- Or maybe easier to measure the resistance of the wire and just multiply by that max current expected to give you the voltage drop. Also there I figure resistance measurements dont account for heating effects. I will do both out of curiosity i.e measure resistance then calculate based on volt drop for a given current.

You can add a safety factor to that to be sure you are covered. > Jim > -- > http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
