Dividing energy from power source

Click For Summary

Discussion Overview

The discussion revolves around how to set up a circuit using 2 AA batteries to power 3 LEDs, ensuring that each LED receives the same voltage and current independently when switched on. The focus is on circuit design and configuration.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks how to configure a circuit so that each LED operates independently without affecting the others.
  • Another participant suggests using 3 separate circuits, each with its own switch and current limiting resistor.
  • A third participant provides a link to a circuit diagram, presumably illustrating a proposed solution.
  • One participant confirms that the suggested setup would work and considers it a good approach.
  • Another participant simplifies the explanation by stating that the LEDs should be wired in parallel.

Areas of Agreement / Disagreement

There is no explicit consensus on the best approach, as multiple suggestions are provided, including separate circuits and parallel wiring. The discussion remains open to interpretation.

Contextual Notes

Participants do not clarify the specific requirements for current limiting or the implications of using different configurations, leaving some assumptions unaddressed.

Who May Find This Useful

Individuals interested in basic circuit design, particularly those working with LEDs and battery power sources.

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.

Thanks

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.
