ANSWER
[tex]12.26\Omega[/tex]EXPLANATION
To find the resistance of the oven, we have to apply the relationship between Voltage and current using Ohm's law:
[tex]V=IR[/tex]where I = current; R = resistance
Therefore, we have that the resistance of the oven is:
[tex]\begin{gathered} R=\frac{V}{I} \\ R=\frac{105.4}{8.6} \\ R=12.26\Omega \end{gathered}[/tex]That is the answer.
