Capacitors are like water tanks but ins tea of storing water, they store energy.  Current can flow through them until they are fully charged.  Once they are full, current will no longer be able to flow throughout them.

Do you want the long video or the short?  Or both?

They also smooth out power.


1. Charge a capacitor

2. discharge a capacitor

3. Use a capacitor to have a light slowly fade (don’t forget your 330Ω resistor

They are not much fun alone but hold on…… you will need it later!



2. use a
