Homework Statement



Two light globes are connected in parallel in a 240V circuit. One light globe has a current of 0.25A flowing through it. The other has 0.41A glowing through it. Which light globe is consuming the most energy and why?


Homework Equations





The Attempt at a Solution



Well I'm stuck with two possibilities on this one:

1) 0.25 A light globe is consuming the most energy as it has less current going through it. (?)

2) Both are consuming the same amount of energy as in a parallel circuit the voltage remains the same in both globes. As both globes have the same voltage, then they are using the same energy. (?)

(I'm leaning towards 2. But both could be incorrect. I just can't see how current is linked to energy as that is a potential difference (voltage) thing.)

ANy help would be greatly appreciated. Thanks

is there an equation to find the energy consumed? if not, find the power of each one ..
