What are electrostatic charges?
Basically, an electrostatic charge is a situation where electrons have been stipped off or added to a body. This is a very simplistic model, but it is easy to understand and is arguably the most common one in the real world. Let's look at it. Electrons hang around parent atomic nuclei. But they are suseptable to being moved. Certainly they shift around in chemical reactions, but let's take a common example using something that is fairly chemically stable - kitchen plastic wrap. Ever pull some plastic wrap off the roll and have it "fold up" on itself? Darn frustrating. But anyone who removes some plastic wrap from a roll like that is participating in an experiment involving electrostatics. The simple act of pulling the wrap off the roll causes electrons to move because you've given them energy. And because the plastic is a pretty good insulator, the electrons can't "get back" to where they were. The electrons have been given energy to move and have been moved by pulling the plastic off the roll. You've separated charges - created static electricity. And now there is an electrostatic charge acting on the plastic and causing it to attract itself and fold up. If we electrostatically "borrow" electrons from an atom, that atom is left with a positive charge. But generally that atom isn't going anywhere. It certainly isn't in that plastic wrap. The electron, however, can be moved with ridiculous ease. We've separated charges, and now have an electrostatic charge between the atom and the electron we removed. If we do this on a large scale by shuffling across a rug on a dry (low humidity) day, we get jolted reaching for the door knob. We separated charges with the simple friction of our feet on the rug. This built up an electrostatic charge, and we "got neutralized" by reaching for the door knob. As long as the materials involved in charge separation aren't too conductive, the charges can't "get home" and a charge will build up. (You can build up a charge rubbing a rubber rod with rabbit fur, but you can't really build up a charge rubbing an aluminum rod with fur.) Moving air, wind, creates friction that can separate charges. The movement of air and moisture in clouds separates charges and builds up an electrostatic charge. You already know where this is going. Zap! Lightning. Cloud-to-cloud, or cloud-to-ground, or ground-to-cloud. Whatever the charge can "work out" to move toward a more neutral state, it will. In the case of lightning, the voltage (difference of potential or electromotive force) will be so great that air will become ionized and this ionized "trail" will conduct the bolt. It could be argued that a bunch of protons constitute an electrostatic charge. And this would be correct. But we don't see that in the "real world" so much as the "more common" contact electrification of static electricity (or triboelectric effect). The bottom line is that static electricity is the voltage created by separating charges. And because the electrons around atoms can be moved fairly easily, creating static electricity is fairly easy. The electrons and the atoms from which they came constitute the static charges, and all they want is to be reunited to neutralize that charge.

Thanks for the feedback!
An object can be electrostatically charged by friction, contact or induction.
It's always stored unless it's conducted away. Thus all insulators have & hold a static charge.
one way in which objects acquire static charge is by friction against two objects which charges the atoms creating static charges/electricity. e.g put on some work boots and s…it on a chair and rub them against the carpet hard and quickly so they gain static charge. then whilst still rubbind touch something metal like a pole.
You can use the electrostatic series to determine charge by looking at the substances higher on the list will always lose electrons and becomes positively charged and the subs…tances lower on the list always gains electrons and becomes negatively charged
it has positive charge and negative charge
when your clothes rub against your skin an electrostatic charge is made.
Through the use of an earthing conductor, for example the black plastic strips that hang from the rear of a car.
The photoconductor drum is charged. The drums is designed so that light causes it to discharge. The areas of charge and discharge are isolated so that patterns can be ma…de. This light and dark areas of the original are transferred as patterns of no-charge and charge to the drum. The toner is a fine powder of microencapsulated ink. It is reverse charged and allowed to get close to the drum. Areas that are charged will pick up the toner, since particles of opposite charge attract each other - areas that are not charged will not pick up the toner. The paper is then charged in the same direction as the drum, but to a higher potential. The paper rolls against the drum, and the particles of toner transfer to the paper, again in the pattern of the original. At this point, the toner can be wiped off the paper, but it goes to the fuser first. The paper is passed through a fuser, which is hot. Under pressure and temperature, the particles of toner melt and fuse to the paper, setting the image.
The build up of electrostatic charge can be prevented by increasing the distance between the two objects.
Charge can also be present on insulators and because these materials do not allow the charge to flow, this is called electrostatic charge
