Could someone explain electric potential?
if the potential is generated from a positive charge it has a positive potential?
if potential is generated from negative charge it has a negative potential
So say that you move an electron from a negative charge starting from r = 2 to r =4.
Since like charges repel is the work done to move the electron negative?
So my question is positive work means work was done on the system (charge) and negative work means work was done by the system?
Where does that negative work go?
Also what is negative potential energy mean?

With a positive energy source, say +12v, the current is pushed through the wire, towards a point which has less potential (like 0v or +5v).
If you have a negative energy source, like -12v, the current is pulled through the wire, from a point that has a higher potential ( again like 0v or +5v). The "-" (negative) only means that the current is moving the opposite way through the wire.
Hope it helps.
