While cooking dinner, Dinah's oven uses a 126.3 V line and draws 8.1 A of current when heated to its maximum temperature. What is the resistance of the oven when it's fully heated?

Sagot :

Given data:

* The voltage across the oven is V = 126.3 volts.

* The current through the oven is I = 8.1 A.

Solution:

According to Ohm's law, the resistance of the oven in terms of the current and voltage is,

[tex]\begin{gathered} V=IR \\ R=\frac{V}{I} \end{gathered}[/tex]

Substituting the known values,

[tex]\begin{gathered} R=\frac{126.3}{8.1} \\ R=15.6\text{ ohm} \end{gathered}[/tex]

Thus, the resistance of the oven in the given case is 15.6 ohm.
