Given information
It is given that the copper wire of diameter 2.2 mm is to be compared with the tungsten wire of same length. It is also known that the resistivity of copper and tungsten are 
and 
respectively.
Step-by-step explanation
Step 1.
Area with diameter, d
The resistance (R) of a resistor is related with the resistivity of it’s material (ρ), it’s length (l) and the cross-sectional area (A) as,
Where, d is the diameter of the resistor.
