Course 2 of 7 · Beginner · 45 minutes
Electrical Fundamentals
In short
Hands-on introduction to electrical concepts. Build circuits to understand Live, Neutral, Earth, and Switched Live. You will understand mains electricity (L, N, E), learn wire colours and why testing matters, build circuits demonstrating Switched Live, use the wiring centre as a connection hub.
