    hoping you can help me. One of my friends is doing IB physics and is stuck on this. I tried to have a go but just failed miserably.
    "what is the p.d between 2 points in a circuit if 1x10^-6 of energy is transformed when 1x10^-9 of charge is moved between the points......."

    I've got as far as V=IR. :rolleyes:

    E = QV

    E/Q = V

    1x10^-6 / 1x10^-9 = 1000 V


    (Energy = Charge x Voltage)
