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.
sorry to bump this but I need a pretty quick reply...
E = QV
E/Q = V
1x10^-6 / 1x10^-9 = 1000 V
(Energy = Charge x Voltage)
