Dividing energy from power source

  • Thread starter hl_world

If I set up 2 AA batteries to power 3 LEDs (each of which had an on/off switch), how would I set up a circuit which allows the same voltage and current to be supplied to each LED when switched on without having to share with other LEDs that are on. If I'm not describing this well, I want the same effect as if each LED had its own power source without affecting the input of its neighbours.

3 seperate circuits with 3 seperate switches and 3 seperate current limiting resistors.
You mean like this?

Yes, that would work and is probably the best route to take.


That's a very cumbersome way of drawing what is really pretty simple: you wire them in parallel.
OK, thanks everyone.
