Cooker

A current of 2A passes through the immersion cooker at a voltage of 230V. What work do the electric field forces in 2 minutes?

Correct answer:

W =  55200 J

Step-by-step explanation:

$$\begin{gathered} U=230\text{ V } \\ I=2\text{ A } \\ t=2\text{ min}\to \text{ s}=2\cdot 60\text{ s}=120\text{ s } \\ P=U\cdot I=230\cdot 2=460\text{ W } \\ W=t\cdot P=120\cdot 460=55200\text{ J} \end{gathered}$$
