## 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
