Question

which is true of high resistance wires?
the cooler the wire, the more the resistance.
the hotter the wire, the more the resistance.
the hotter the wire, the less the resistance.

Explanation:

According to the relationship between temperature and resistance of metal wires (a common type in such contexts), for most metals, as the temperature (hotness) of the wire increases, the thermal agitation of atoms/molecules increases. This causes more scattering of charge - carriers (electrons in metals), which in turn increases the resistance.

Answer:

The hotter the wire, the more the resistance.
