Post the question, here or on forums and someone will help.

I updated my folder with the definitions for G481 and G482 and some standard answers for them too.

Not coherent as Time period is different; so the frequency of the two are different so there is not a constant phase relationship.

I'll probably update my folder when I finish the year with stuff that I think is useful; unless of course I fail it in which case I will just be sad.

Can somebody explain which forms of the power equation to use when working out power and power dissipated, is it just the ones with resistance in them?

P = w/t = IV = I^2R = V^2/r
