Are you given more information?

astrophysics · Answer

Can you put a image of the full problem

mtalhahassan2 · Answer

Ok sure wait a sec

mtalhahassan2 · Answer

So basically I guess we are find the E for energy

astrophysics · Answer

Yes we need E it seems, but we are lacking information, at the moment or I'm just really tired and not seeing it :P, but please post an image of the problem!

incomplete information

you can say that the total amount of charge that has passed any given point in circuit = It = 15 * 20 * 60, but that's it.

mrnood · Answer

you are lacking information

Energy = power x time

power = volts x amps

unless you know the voltage you cannot answer

You maybe need to assume it is your mains voltage in your country

As I suspected, that for confirming everyone :)
