Hi all. I am a part-time college student majoring in Electrical Engineering
Technology. I have been trying to learn as much as I can on my own since I
was twelve; about ten years now. The earliest material I found was in books
and experience in taking things apart. I learned that electrons flowed out
of the negative terminal of the battery, through the circuit components, and
back into the positive terminal. Hence, I have always designed my projects
around a positive ground point. No problems there.
Well for the past year I have finally gotten into the hardcore
electronics-related classes at the college. Some material is familiar, but
most of it is new. I am doing well however I have difficulty with the fact
that the modern textbooks are showing the circuits using a negative ground.
This seems backwards. I know the circuit will still work the same way, but
it's hard to get myself to think in the negative-ground sense. If I look at
a positive-grounded circuit, I can envision the electrons and make
calculations without difficulty, but it's a different story with negative
ground for me.
What is anyone else's takes on this?
