Discussion Overview

The discussion revolves around understanding wiring schematics for electrical engineering, specifically focusing on the concepts of VCC and ground connections in a breadboard setup. Participants are addressing foundational concepts that are essential for beginners in electrical engineering.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses confusion about wiring VCC and ground, seeking clarification on their connections to the power source.
  • Another participant provides links to resources that may help with understanding breadboard wiring.
  • Some participants affirm that VCC typically connects to the positive terminal of the power source and ground to the negative terminal, but note that this can vary in certain situations.
  • There is a caution mentioned regarding floating power supplies, indicating that ground may not always correspond to the negative terminal of the power supply.

Areas of Agreement / Disagreement

Participants generally agree on the basic connections of VCC and ground, but there is acknowledgment of exceptions and variations in different contexts, indicating that the discussion remains somewhat unresolved regarding specific scenarios.

Contextual Notes

There are limitations in the discussion related to the assumptions about power supply configurations and the varying definitions of ground in different contexts, which have not been fully explored.

Who May Find This Useful

Novice electrical engineering students or individuals new to wiring schematics may find this discussion helpful as they navigate foundational concepts in their studies.

I just started a EE class and the teachers just threw up there without really explaining everything. Everyone's lost. I tried to Google, but couldn't find anything.

I have a breadboard, and I have a schematic I need to wire, but I do not really understand how to wire the VCC and ground (symbols). From what I've been told, VCC goes to power source positive, ground to power source negative. Is that right?

I'm sorry for the painfully stupid / obvious questions. Course textbooks come in two weeks and the teachers are overloaded.

Mmhmm.

Don't worry about "noob questions". Everyone has to start somewhere :)

Most of the time with floating power supplies you want ground to be that power source negative. In your case this is probably what you want.

Just be aware that there are cases where ground doesn't mean the negative terminal on a power supply.
