A relatively simple circuit with a battery running an LED and various capacitors, which can be attached in parallel by pressing the switches and the last branch to the right includes two capacitors in series with each other. Play with the circuit as you like, try to turn it on and off and press the various switches and then watch what is happening to the voltage over the LED and its attached capacitors.
Have Fun! 🙂
NB: This circuit is inspired by the Basic Electronics series by Simply Electronics, number 11.
