charge(Q)
-
-
if you rubbed a balloon on a jumper, electrons would transfer meaning the jumper now had a negative charge
Charge is pushed around the circuit, however it does not produce the charge as that is already in the metal wires
-
potential difference(V)
-
the potential difference across a cell/battery tells you the amount of force on the charge going round the circuit
The potential difference also tells you how much energy can be transferred to the components in the circuit by the charge

-
resistance(Ω)
-
-
you can use resistance to explain why current decreases as you add more bulbs in a series circuit- adding more bulbs increases the resistance so the current is less
