I am currently stuck on how to work out this question.

Calculate the energy transfer in 1200s in a component when the p.d across it is 12V and the current is 2A.

I have been attempting it for at least half hour but still no luck.

Can somebody please help me out on how to work it out :)

Do you know how to calculate the power dissipation? Do you know the relation between power and energy?

I have a text book here with equations in but they are hard to type because they have the Delta triangle in them. But if you could further explain these to me that would be great.

If you can't tell me in words what the power dissipated in a resistor is, it sounds like you need to study more. Try reading the textbook.
