Year 11
Electric Circuits & Electrical Safety
Cover potential dividers, relays, diodes, circuit characteristics, and electrical safety through the opening Year 11 sequence.
Part of Year 11 CIE Physics 0625.
Topic Overview
What students will cover
This topic extends Year 10 circuit work into more useful circuit components and control systems. Students should see how potential dividers, relays, and diodes are used in real circuits and why safe electrical design matters.
Keep the practical and applied thread clear so the topic does not become just a list of devices.
