Given information
It is known that at the resistivity of tungsten is and that of aluminum is It is also known that for aluminum, the temperature coefficient of resistance is
Step-by-step explanation
Step 1.
The resistivity at temperature is correlated to the reference temperature and the resistivity at that temperature is as,
The varying resistivity of due to temperature
Here, is the temperature coefficient of resistance of the given material
