Power station → your lamp. Watch it travel!
3 Ways to Think About It

Marbles in a Tube
Push one in → one pops out. Wire is already full!

Water in Pipes
Pump = voltage. Flow = current. Tap = switch.

The Domino Push
Each domino barely moves, but the push races!
Mission 1
The wire is already full! 🟢
A wire is packed with electrons. A switch just pushes them.
🎯 Tap 3× — watch ALL electrons wiggle!
Mind-blowing
🐌 vs 🚀
Push = fast. Electrons = slow!
Light turns on instantly because the push is fast, not the electrons.
Mission 2
Make some juice ⚡
Spin the handle! Magnet shoves electrons. Faster = brighter.
The real question
What spins the magnet? 🤔
Pick one above 👆
🔥 STEAM. Heat → steam → turbine → magnet spins.
💨💨💨
🌊 FALLING WATER. Water drops → wheel → magnet. A dam!
💨 WIND. Air pushes blades → magnet spins.
☀️ SUN — NO SPINNING! Light pops electrons loose directly.
~80% of electricity = spinning a magnet. Same trick, different fuel!
Mission 3
Build the route 🗺️
The magnet is hundreds of km away! Order the stops.

Why go HIGH?
The voltage trick 🎯
Long trip = wires get hot. Push voltage UP for the trip, DOWN at your house.
⚠️ 230 V is still dangerous. "Stepped down" ≠ "safe to touch".
Mission 4
Close the loop 🔁
Every device needs two wires: one IN, one BACK.
A · Live
B · Neutral
Switch
C · Spare
🎯 Task 1: make the lamp glow.
Electrons need a round trip. Half a loop = dead end!
Mission 5
You're the grid boss 👷
Electricity is made the moment you use it! Keep balanced for 30s.
