Homework Statement
The copper windings in an electric motor have a resistance of 54[Ω] at 200.
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 00C R0 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 t2=2860C
