Hi, I'm new, if I forgot something in asking my question the RIGHT way please direct me to the correct way.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A current of 0.3A is passed through a lamp for 2 minutes using a 6V power supply. The energy dissipated by this lamp during the 2 minutes is:

2. Relevant equations

P=VI?

3. The attempt at a solution

So I took V*I=1.8W for Power

And took 1.8W dividing 120s to get 0.015J

BUT the correct answer is 216J, I don't know how that is. Please help, thanks.
