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 result:

W =  55200 J


U=230 V I=2 A t=2 mins=2 60 s=120 s  P=U I=230 2=460 W W=t P=120 460=55200 JU=230 \ \text{V} \ \\ I=2 \ \text{A} \ \\ t=2 \ min \rightarrow s=2 \cdot \ 60 \ s=120 \ s \ \\ \ \\ P=U \cdot \ I=230 \cdot \ 2=460 \ \text{W} \ \\ W=t \cdot \ P=120 \cdot \ 460=55200 \ \text{J}
