Hi, I'm new, if I forgot something in asking my question the RIGHT way please direct me to the correct way.
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:
P=VI?
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.
