Outcomes

Reinforce Current is the rate of flow of charge Q = I × t

Introduce idea of free electron movement in metals- which way do they flow? Conventional current.

Show charge flow in an electrolyte – ions = charged particles

Specification References

2.15 understand that current is the rate of flow of charge

2.16 recall and use the relationship between charge, current and time : charge = current × time

2.17 recall that electric current in solid metallic conductors is a flow of negatively charged electrons
