    Mate don't *urge* everyone to do it, you'l raise the grade boundaries as people will do better, making it harder for you to get your grade! Remember OCR wants a finite number of people getting particular grades, regardless if people are cleverer or not. OCR are cheaky I know but they are still not a joke, they can easily screw us over in the next paper.
    But yeah, that's just selfish and makes you sounds like a c**t.

    As it takes long for me to upload these, I will post 2 here, and if you want the other topics let me know. I hope they help.

    Hi,
    These are really helpful, is there any chance you have Capacitors notes?
    I'm pretty bad at that part of the course

    Glad they helped.

    Capacitors one: http://www.mediafire.com/download/ic...Capacitors.pdf

    Main thing about capacitors is to understand that the charge is shared equally between them when they are in parallel, and that the charge for each capacitor is the same when in series. If you understand this deeply, you will be good.

    yh that's very true and the p.d is shared in series right?

    Yes exactly, just like any circuit for the p.d.

    since current is the third thing would it be like charge i haven't seen anything on it yet

    What do you mean, current is the third thing?

    i mean cuz with capacitors u have voltage, charge and current as the main things that change( u know with the graphs), apart from capacitence

    nvm just seen it, current is like charge in the way it is shared too

    Well current is due to the movement of charged particles, so current is charge.
    That is why in series they have same charge because the current is the same in the series circuit which basically the charge. And since the current is shared in parallel that is why the charges of the capacitors are shared.
