Potential of the terminals on a DC power supply

Click For Summary
SUMMARY

The discussion centers on the voltage potential of terminals on a 12VDC transformer used in an educational setting. The positive terminal is +6V above ground potential, while the negative terminal is -6V below ground potential. The presence of a third terminal labeled GND could provide additional clarity regarding the grounding configuration. Users are encouraged to consult the manufacturer's documentation for definitive information.

PREREQUISITES
  • Understanding of DC voltage and potential differences
  • Familiarity with transformer operation and terminal functions
  • Knowledge of grounding concepts in electrical systems
  • Ability to interpret electrical schematics and manufacturer documentation
NEXT STEPS
  • Research the specifications of 12VDC transformers
  • Learn about grounding techniques in electrical circuits
  • Examine the role of GND terminals in DC power supplies
  • Review manufacturer documentation for electrical components
USEFUL FOR

Electrical engineering students, educators in electronics, and hobbyists working with DC power supplies will benefit from this discussion.

Hi there
On a 12VDC transformer we use at school. Is the positive terminal +6V above ground potential and the negative terminal -6V below ground potential?
Thank You

Maybe, maybe not. One clue might be if there's a third terminal labelled GND.
