Wisdom..? You want wisdom, too..? You're a hard one to please.
In theory, and as a general 'rule of thumb', the higher the resistance of a pick-up, the 'hotter' the output, but, as SD states in the link above, it's not that simple. Electrically, the longer the wire used for the coils (equates to number of winds...), the higher the resistance, and the thinner the wire (no way of knowing what gauge the wire is, generally...), the greater the resistance, for the same length. Soooooo... Thin wire with few winds could be high resistance; thicker wire with fewer winds could be the same resistance. The output would be different, however. The resistance, as a measure, and on its own, does not, therefore, tell us much. It could be useful when testing two pick-ups from the same maker, but even then, only as a guide.
What is the real reason for the question, though..? Are you looking at any specific pick-up related issue..?
