⚡ Sources of Electricity
Electricity powers robots — but where does it come from?
- 🔋 Battery – Stores chemical energy (e.g., AA, 9V, button cells)
- ☀️ Solar – Converts sunlight to electricity (used in solar robots)
- 🔌 Wall Socket – Supplies power from the grid (used in homes/schools)
- 🌬️ Wind/Water – Spins turbines for eco-friendly power
- ⛽ Generator – Uses fuel (diesel/petrol) for backup electricity
