Hey there,
I know this is a stupid question, but here goes:
Why does my power supply have only a (+) and a (-), whereas the more expensive power supplies have a (+) , a (-) , and a GND?
Isn't the (-) and the GND the same thing? I mean, in every schematic I look at, there is only the latter two.
I know it has something to do with digital, but I haven't yet grasped the concept of +5V, 0V, and -5V. I am still learning the basics and I only know about the "binary" system of (+) and (-). How does a battery (or another DC power source) put out 3 different voltages?
If anyone can help me understand this I will be most grateful.
