Given information
It is given that the copper wire is at 20°C and resistance is to be raised by 12%. It is also known that for copper, the temperature coefficient of resistance is 0.0068 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,
Where, is the temperature coefficient of resistance of the given material
