Model electronics 101, lesson 3, setting up a simple parallel circuit

Great series please do some more they are both informative and helpful in getting started. All the best

5:03 lol you powered on the LEDs

When activating the switch and the one set of LEDs go off, and the others stay the same brightness ... my understanding is that this is because the other parallel series have their current limited by their own resistor. The only time you should see an increase in brightness is if there is less current available from the source (battery) than is limited by the resistor, and when you turn one of the parallel series off you should see an increase in brightness as the current becomes available.

Thanks for the video..

tahahaha im not an expert xD

In conclusion to my first post below, one of the advantages as I understand it to using parallel circuits, is to be able to run multiple strands of LED's with consistent brightness. If you put 20 LED's on a single series circuit, you'd have 20 very dim LEDs. Break that into something like 4 or 5 circuits tied together like you demonstrate in this video (i.e. in paralell) and you can get past the problem of voltage drop. Thanks again for the great tutorials!

Face, great videos. I've learned a lot. There's one thing I don't think you went over, but I'd have loved to have learned in this particular video, which is voltage drop. I wasn't certain if there was a limit to the number of LED's that could go on a circuit, but it turns out there is. For instance, a 9v battery is only going to be able to support 9v worth of pull from however many LED's you try to put on a circuit. If you use 3 white LED's rated at 3.2v (9.6v total) you'll lose brightness.

Thanks for posting this, its very helpful!

Have a good one!
