Circuit Confusion Notation Schematic Symbols

Click For Summary

The discussion centers on the confusion surrounding schematic symbols, particularly regarding terminals that can represent either an open circuit with a voltage source or a closed circuit with a voltage/current source. Participants highlight the ambiguity of using a simple terminal symbol instead of a clear voltage source symbol, leading to misunderstandings about whether the circuit is open or closed. The ground symbol's role is also debated, with some asserting it establishes a reference for voltage measurements, while others argue it complicates the interpretation of floating voltage sources. Ultimately, the conversation emphasizes the need for context in circuit schematics to clarify the intended meaning of symbols. The resolution of these confusions is crucial for accurate circuit analysis and understanding.

"Grounding" conductor is green here and i think brown in EU.

In Australia and EU.
Green with a yellow stripe is Earth, (it was once green).
Brown is Active, (it was once red).
Light blue is Neutral, (it was once black).
The colours were changed to avoid the common red-green colour blind hazard that swapped Earth and Active.
