Repair #3:
The energy storage
Now, you'll notice the light works, but switches off as soon as you stop turning the handle. If only there was a way of storing the energy...
📹 How is energy produced and stored?
🧐 Why will the light not stay on?
A) The handle is not turning quickly enough
😅 Try again
Turning the generator faster produces a higher power, which makes the LEDs brighter. With no way to store the energy, when the generator stops turning, it stops producing power.
B) There are no batteries attached
✅ Correct!
No battery is currently connected! We need to add a battery to the circuit so that the power can be stored and the light can stay on.
C) The batteries have run out of power
😅 Try again
We are generating power by winding up the handle, which should charge any connected batteries.
D) The LEDs are broken
😅 Try again
If the LEDs were broken, they wouldn't turn on at all. In this case, they do switch on, but just can't stay on!
