    right so im a bit confused. doing the variation of current with p.d, what does the graph have to be? do u put I on the Y, V on the x, or do u have to do those stupid things like putting it 1/V instead of just V etc?

    You just plot P.D. against I, because V is directly proportional to I so no need to plot its inverse, and as greenbetty said you plot P.D. on the x-axis. Generally, what you are varying goes on the x-axis and what you measure goes on the y-axis,so if you can't remember in the exam just do that.

    i'd put money on that not coming up. if it does i think it will be asked with another question, maybe with conservation of momentum or something

    i take that back
    :P
