For the Edexcel AS exam, do you have to know the Kirchoffs laws? I know the simplified principles eg:

The sum of the EMF around a circuit loop = sum of the PD around the loop

But I know that wouldn't be the way you write it if they asked for it in the exam. So do you have to learn the exact law?

Try and find a mark scheme with that question in and see what variations they accept?

To be honest i think that definition would be enough to get full marks. Don't take my word for it but i'm not sure how much more you can add to it.

Kirchhoff’s first law: the total current arriving at a junction in a circuit must equal the total current leaving the junction.

Kirchhoff’s second law: The sum of the potential differences round any closed loop in a circuit must be zero.

Those definitions should be good.

True, should have thought of this
