Hey,
I am just done studying my Master in electrical engineering and when I in my studies came across a ground connection, it has always been used as the return path for the +5 V input or whatever input being used.
However, now I am trying to understand the purpose of ground connection on a system level. For instance a system being fed with a single phase systems with phase, neutral and ground. I know that for instance in the car, the ground or protective earth that I understand it is called is connected to the chassis of the car. Can anybody explain to me why?
In the electronic systems we develop at work, I have also understood that the protective earth should be connected to the box surrounding the electronics. Why?
Can anyone explain or give me a hint on where to find a good book/electronic resource to read up on regarding this?
I've been reading on wikipedia for instance but I have a hard time to find what I am really looking for.
Thanx
