Question

While cooking dinner, Dinah's oven uses a 140.6 V line and draws 6.7 A of current when heated to its maximum temperature. What is the resistance of the oven when it's fully heated?

Answer 1

Given data:

* The voltage across the oven is V = 140.6 volts.

* The current through the oven is I = 6.7 A.

Solution:

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

`\begin{gathered} V=IR \\ R=(V)/(I) \end{gathered}`

Substituting the known values,

`\begin{gathered} R=(140.6)/(6.7) \\ R=21\text{ ohm} \end{gathered}`

Thus, the resistance of the oven is 21 ohm.
