CAIE IGCSE Physics 4.2.2.3 Electrical conduction in metals in
Practise linking current in metals to mobile electrons and using metal structure to explain why copper wires conduct well.
How this is tested
- identify free electrons as the moving charged particles in a metal wire
- explain good metallic conduction from delocalised electrons in the structure
