GCSE Physics P2 - Electrical Safety with Fuses, Circuit Breakers and RCCBs

A completely resourced lesson on GCSE Physics P2 - fuses, circuit breakers and RCCBs including key content from AQA exam specification.

Starter reviews previous unit content on plug wiring and AC/DC current which leads to fuses.

Electrical safety is discussed through the effects of electric shocks and resistance is briefly revisited, reviewing previous P2 content. Resistance in a wire is related to the operation of fuses which is then detailed ( a nice demo is included in the comment box but alternatively a video can be shown).
Circuit breakers and their function is detailed with animations and videos with key questioning on functions.
A written task reviews fuses and circuit breakers.
The detail required by the exam specification is provided (with an alternative slide for classes that would want to know more).
The importance of earthing is explored through questioning (relating back to P2 Statics).
The plenary task uses pictionary to review all key concepts.
