Electricity and Electronics
2 original lesson summaries in this topic collection.
Topic overview
- Voltage (V), current (A) and resistance (Ω) relate by V = IR; power P = VI.
- DC flows one way; mains AC (230 V, 50 Hz) is used because transformers change voltage easily.
- Earthing and overcurrent devices protect wiring; RCDs protect people from leakage.
- Double insulation, AS/NZS 3000 and licensing underpin electrical safety.
