Where there is an imbalance of charges present, there will usually be voltage differences.

Charges exert forces on each other and create an electrostatic field in which various effects occur. Like charges repel each other, and unlike charges attract each other.

If like charges have built up in a region, they repel each other, and if they are able to move, they will move apart and gradually spread out and dissipate. Unlike charges will be attracted and move together.

When opposite polarity charges are sufficiently close together, their effects cancel, and the charge is said to be neutralized.
