Given information
It is given that the initially at 
the resistance of the filament was 12Ω, which becomes 140Ω when being hot. It is also given that the temperature coefficient of resistance is 0.0045 per °C.
Step-by-step explanation
Step 1.
The resistance R at temperature 
is correlated to the reference temperature and the resistance at that temperature 
as,
Here, 
is the temperature coefficient of resistance of the given material
