Electric work

Calculate the work done by the electric forces passing the current of 0.2 A through the bulb in 10 minutes if the bulb is connected to a 230 V power supply.

Correct result:

W =  27600 J


I=0.2 A t=10 min s=10 60  s=600 s U=230 V  P=U I=230 0.2=46 W W=P t=46 600=27600 J

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
