What is the power rating of a heating coil with a resis-tance of 12 12 that draws a current of 20 A?

Answer :

According to the problem, we have the following

[tex]\begin{gathered} R=12 \\ I=20 \end{gathered}[/tex]

We have to use Ohm's law

[tex]V=I\cdot R[/tex]

Let's replace the given information

[tex]V=20\cdot12=240[/tex]

Hence, the power is 20 Volts.
