    Quick question, probably been asked a few times before:

    If they ask to us derive the energy stored by a capacitor, for 3 marks say, how do we gain all 3 marks?

    Isn't it just Work Done = QV. So Energy stored equals the area under a Q-V or V-Q graph, which equals 1/2 x Q x V?

    if people want to do a model answers/unofficial markscheme, I'm going to try and store my answers to the multiple choice in my calculator, ie A=1, B=2 etc., if others do the same we can build up a good idea of whats right or wrong, instead of trying to remember a 25 letter string

    Let A=1 B=2 C=3 D=4 and you can store a whole 25 letter string in your calculator....

    If the string is:

    ABDCBDACCDBDCAA

    124324133424311

    For example... Convert back to letters after and you have your 25 answers

    or you could just note down all your answers from 1 to 25 on that little paper slip with your candidate and centre number/name, and take it with you out of the exam?

    How would you answer a 6 mark question on transformers about heat loss? Like how would you link faraday's law and Lenz's law to it?

    Is it ok if you only filled the pink sheet for the multiple choice? And not the actual booklet
