    YES! I'm not saying its right because me and you have got it, but I got 1.56A, 1.25V and 3 ohms, always feels good when someone else gets the same

    What did everyone get for electricity qs. I got 1.1 a

    What did you guys get from the resistance of the internal resistor question.
    i got 3 Ohms for the internal resistor

    Which one was this mate?

    for the question where you had to use the graph to work out current, did anyone else get 1.6?

    I'm a ****ing idiot. Tried to be clever by taking 1.9 from 6 to get the power dissipated to work out the current. What was I thinking.

    i did my answers to 2 s.f. so would it still be correct ?
    It should be alright did you get similar numbers to me? I suck at electricity...

    What did everyone put for the very last question? (How would the reading change if the Voltmeter was put over R)

    I got the current as 1.54A, voltage Y as 2.23V and r as 3.1 ohms

    Does it matter if you used 3s.f. as long as you were consistent throughout the question? Or should you of used 2? for the graph question? as the emf and resistance they gave us were both to 2?

    I put it would increase with temperature. Increase in temp decreases resistance and PD across thermistor. A larger proportion of PD then goes to R so the voltmeter reading would be higher. I have no idea if this is right or not. :L

    I put pretty much the same as you but in a lot less detail:') ahhh well, just have to wait and see

    I got this too, hope we don't loose marks for rounding errors
