1. Hi guys!
So I created this thread for unit 2 physics. Let's revise, share our ideas and clear our doubts here!
2. Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

You can also find the Exam Thread list for A-levels here and GCSE here.

Just quoting in Puddles the Monkey so she can move the thread if needed

I guess it follows from Ohm's law (R=V/I) where R=r, total V=V+E, and I=I.
7. Need help in this question thanks....

It's basically about energy levels which are of restricted values. So when an electron gets exited and then drops from a higher energy level to a lower energy level, it emits energy of only certain values, therefore since E=h*f, photons are emitted and the light has only certain discrete frequencies. Hope i explained it well

12. What does a resistance against potential difference for a filament lamp look like and why?
