Johnny Graves · Answer 1

A) A warm wire

Explanation:

A warm wire has the most resistance. Heating the metal wire causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. Heating the wire increases resistivity.

In which of the following conditions would there be the most resistance?-a warm wire-a wide wire-a short wire-a cool wire
