This is the flow of electrical charge and is made up of negatively charged electrons
potential difference
current
resistance
This is anything in the circuit that stops the flow of charge. This value is different depending on the component in the circuit.
resistance
current
potential difference
this is the driving force or push from the power source, usually the battery. Without it, the current cannot flow.

What is the equation that links time, charge flow and current?
charge flow = current / time
charge flow = time / current
charge flow = current x time
current = charge flow x time
what is the equation that links potential difference, current and resistance?
potential difference = current x resistance
potential difference = current / resistance
current = potential difference x resistance`
current = resistance / potential difference
