## Homework Statement

The copper windings in an electric motor have a resistance of 54[Ω] at 20

^{0}.

Later the resistance was 60[Ω], what is the temperature

## Homework Equations

$$R_1=R_0(1+\alpha t_1)$$

α=0.00393[1/

^{0}]

## The Attempt at a Solution

At 0

^{0}C R

_{0}is: ##54=R_0(1+0.00393\cdot 20)\rightarrow R_0=50.06##

##60=50.06(1+0.00393\cdot t_2)\rightarrow t_2=50.5^0##

It should be t

_{2}=286

^{0}C
