Electricity Recap

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.

• current

• resistance

• potential difference

This is another word for voltage

• current

• potential difference

• resistance

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
