Simple electrical circuits with 3 or 4 LEDs and illustrating the difference in driving them with respectively a constant voltage or a constant current source. Just click on the switches and see what happens with voltages and currents in the circuits, when the fourth diode is attached or not.
NB: These circuits were inspired by or taken from the Basic Electronics series by Simply Electronics at YouTube.
