Ritmo2k Posted January 20, 2006 Report Share Posted January 20, 2006 I have been out of electronics for too long. Can someone point me to a definition to understand what a +/- powersupply is, and how you attain it? Specifically like a computer type switch mode ps, what does a +5 and -5 volt mean?And I dont mean the generic polarity of a trivial ps either;->Thanks Quote Link to comment Share on other sites More sharing options...
indulis Posted January 20, 2006 Report Share Posted January 20, 2006 A power supplies output is only the voltage potential between the terminals. It's polarity is determined by which terminal is used as the reference. Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted January 20, 2006 Report Share Posted January 20, 2006 just for a beginner :for any circui to function with reliablity except for special autotransformers,+/-5V is equivalent to 0 and 10V supply.potential difference requires no reference but a potential does.thats it. ;D Quote Link to comment Share on other sites More sharing options...
EdwardM Posted January 20, 2006 Report Share Posted January 20, 2006 Hi Ritmo2kI've tried to answer what I think is your question with a diagram...+5v means a positive supply relative to some common terminal and likewise -5v means a negative supply relative to some common terminal.Hope that helpsEd Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted January 23, 2006 Report Share Posted January 23, 2006 i always compare voltage with water levels.believe me there is perfect analogy.ive seen peopleconverting electrical problems to hyraulic problems and solve them.!!!!!!
