Discussion Overview

The discussion revolves around identifying and reconstructing the circuits of two black box setups, one with a switch and one without. Participants explore the notation used in circuit diagrams and share insights on the symbols for light bulbs and lamps.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in understanding the configurations of two black box circuits, noting the connections to a 6V power source and the brightness of lamps.
  • Another participant questions the notation used in the circuit diagrams, specifically regarding the colors and symbols represented.
  • A participant clarifies that the colors refer to the ports for wiring connections and emphasizes the goal of reconstructing the black box circuits.
  • Some participants express uncertainty about the adequacy of the provided information to understand the problem fully.
  • Several participants discuss the symbol for a light bulb, noting variations in usage across different regions and educational contexts.
  • One participant shares their suggested circuits, indicating that they believe these would yield the observed results.

Areas of Agreement / Disagreement

There is no consensus on the clarity of the original problem or the adequacy of the information provided. Participants have differing views on the notation and symbols used in circuit diagrams.

Contextual Notes

Some participants reference different symbols for light bulbs and lamps, indicating a potential limitation in understanding due to regional differences in electrical symbols.

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:
