AS AQA Physics PHYA1: Particles, Quantum Phenomena &amp; Electricity

I believe it's when there's no pd across it - ie the work function is the minimum energy needed by a conduction electron to escape the surface of a metal at zero potential.

Ah thank you!

No worries! Good luck! How are you revising for it? :smile:

Hi. Sometimes when I do past papers I feel confident on electricity, then at other times I can't seem to do any of the questions. I started revising for physics early and I was getting As in the past papers that I was doing now I really struggle with electricity. The rules seem to be changing in each past paper.

I can totally relate. I got an A in my mock in January when I'd just finished learning it and recently got a C. Explain that one...

Any inklings on what the six marker will be guys??!

Well got to keep at it the highest I got was a C :/ but this weekend is devoted to Maths and physics...
pits easy ish stuff but getting the marks is difficult I find

Yeah I agree - I've got maths and physics obviously but also history coming up very soon this week, but history is on Thursday so I might prioritise it less this weekend...

The physics mark schemes are so specfic!

I could not do history aha, next week will be interesting though!
Monday - core 1
Tuesday - Physics
Wednesday - biology
Thursday - core 2
-.-

It's nice they're all on different days though! Core 2 & History on the same day will suck! What's your prediction for the 6 marker for physics? :smile:

Probably on quantum, as the 2013 one was particles and electricity. As we've had most the possible electricity questions in previous papers, it will probably be something hard as well :frown:
