Homework Statement
This question comes from one of my previous exam
and I still couldn't solve it after days of trying
hope someone can guide me through this thanks
A copper wire has a resistance of 10Ω at 10°C.
Determine the resistance of the wire at 80°C.
Given that the temperature coefficient of the wire is 0.00393C-1 at 0°C.
Homework Equations
R2 = R1(1+[itex]\alpha[/itex]1*ΔT)
The Attempt at a Solution
I don't know where to start when I don't have the temperature coefficient of R1
I know this may look silly because it maybe very easy to all of you
but please help me on this
