Since you are talking about conductors, a high temperature one will have a high resistance. Reason being that the distance between the conduction and the valence band keeps on increasing on the increase of temperature.
A substance is said to be conducting if it has FREE electron in its conduction band. Since the distance b.w the to bands increases, less number of electrons are able to jump from valence band to conduction band, hence more resistance...

What is effect of temperature on conductor?
Increasing the temperature of a conductor will typically increase its electrical resistance, reducing its conductivity. This is due to increased collisions between electrons and atoms in the conductor, hindering electron flow. Extremely high temperatures can cause a conductor to ultimately melt or break down.
Is niobium a heat conductor?
Yes, niobium is a good conductor of heat due to its high thermal conductivity. This property makes it useful for applications where heat transfer is important, such as in superconducting magnets or in high-temperature environments.
What is the maximum amount of current a conductor can carry continuously without exceeding its temperature ratings?
The maximum amount of current a conductor can carry continuously without exceeding its temperature rating is typically determined by the conductor's ampacity rating, which is based on factors such as the conductor material, insulation type, and ambient temperature. It is important to adhere to these ampacity ratings to prevent overheating of the conductor.
Is your body a good conductor of heat?
Yes, the human body is a poor conductor of heat due to its high water content. This means that heat does not easily flow through the body, helping to maintain a relatively constant internal temperature.
What 4 things affect resistance?
The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.
Is boron a good conductor of electricity?
Boron is not a good conductor of electricity at room temperature, but is a good conductor at a high temperature.
Which element at room temperature is a poor conductor of electricity and has a relatively high electronegativity?
Sulfur has relatively high electronegativity and is also a poor conductor of electricity at room temperature. Fluorine has the highest electronegativity and copper is a good conductor of electricity.
Is glass a poor conductor?
It depends on whether you mean heat conductor or electrical conductor; in either case it is a poor conductor at room temperature; but at very high temperature it is a good electrical conductor but still a poor heat conductor
Of the elements oxygen zinc and iodine which one is likely to be poor conductor of electricity and a brittle solid at room temperature?
Iodine is likely to be a poor conductor of electricity and a brittle solid at room temperature. It is a non-metal with properties that make it a poor conductor of electricity and a brittle solid.
Which element would most likely be shiny solid at room temperature and a good conductor of heat?
Co
What is effect of temperature on conductor?
Increasing the temperature of a conductor will typically increase its electrical resistance, reducing its conductivity. This is due to increased collisions between electrons and atoms in the conductor, hindering electron flow. Extremely high temperatures can cause a conductor to ultimately melt or break down.
Why GaAs is preferred to Si for high temperature operation of semi-conductor device?
GaAs has high mobility compare to Si
Which element would most likely be a shiny solid at room temperature and a good conductor of electricity?
Gold, silver, copper.
Is niobium a heat conductor?
Yes, niobium is a good conductor of heat due to its high thermal conductivity. This property makes it useful for applications where heat transfer is important, such as in superconducting magnets or in high-temperature environments.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
When electric currnet flows through a conductor then temperature of conductor will?
increase
Which type of element has the following general properties solid at room temperature high luster good conductor of heat and electricity malleable and ductile?
The element you are describing is likely a metal. Metals are typically solid at room temperature, have a high luster or shine, are good conductors of heat and electricity, and are malleable and ductile, meaning they can be hammered into thin sheets and drawn into wires, respectively.
