    Box Circuits
AI Thread Summary
The discussion revolves around identifying the circuits of two black box setups, one with a switch and one without. The user seeks assistance in understanding the connections and the notation used for the circuit diagrams, particularly the symbol for a light bulb. Participants clarify that the circle with an "x" represents a light bulb and share resources on electronic symbols. The conversation highlights regional differences in symbol usage, with references to educational practices in the UK, US, Australia, and New Zealand. Ultimately, the user expresses gratitude for the help received, indicating that their problem has been resolved.

Hi

I'm experimenting with some black boxes and I'm trying to figure out what's their circuit. I can't seem to find what these two circuits could be.. Could someone please help me out?

The purple crosses mark which ports are connected to the power source (6V). The yellow marks show how hard every lamp is burning.

Circuit 1 w/ switch:

The second setup shows the lamps when the switch is pushed.

Circuit 2 without switch:

The purpose is to get something like this: (this is from another black box I tried)

If anyone could help me with this, I'd be glad! Thanks!

So what is the "Green, Red, Blue"? Are those lights? is that the circuit diagram? I'm not familiar with that notation.
 
@scottdave They refer to the colors of the ports where you can plug the wires into. The wires are connected to a power supply (6V). The purpose is to get a circuit that you could rebuild the black box with.
 
Is this a problem you made up yourself?

There is not enough information for us to understand what you mean or what you are trying to accomplish.
 
I have attached my suggested circuits.

OK, the circle with an x is a light bulb. I hadn't seen that used before.
 
I think both circuits that you have drawn would produce the results that you observed.

The Wiki article shows it as an incandescent lamp used as an indicator. It is taught to the kids at school in the UK. I don't like the symbol myself.

And in the US, the Ladder Diagram used in industrial control schematics shows this for a lamp (although the Switch symbol shown here is rarely seen):

Yeah, pretty standard here in Australia and New Zealand as well :smile:
