 PowerPedia:Electrostatics - PESWiki
Electrostatics is the branch of physics that deals with the forces exerted by a static electric field upon charged objects.
Because of the electric field's relationship to and interaction with magnetism, electrostatics is a subfield of electromagnetism.
Because the electric field is irrotational, it is possible to express the electric field as the gradient of a scalar function, called the electrostatic potential (also known as the voltage).

Since the golden age of electrostatic experimentation was the 17th century, these experimenters and the Wimshurst machine have become confused in the minds of the public.
Electrostatics is based on Gauss's Law, and on the law that the line integral of the electrostatic field around any closed curve is zero, which is a form of conservation of energy, and which we tacitly assume in this article.
The electrostatic potential of the charge on the plate is raised by separating it from the resin; this requires work to be done against electrical forces (the attraction of the charges), as in all cases when we gain electrical energy.

  From Electrostatics to ESD
A hundred years ago, it was all known only as electrostatics, a well-researched field that formed the basis for the teaching of electricity in general.
Electrostatics had its own system of units based on the mechanical units of centimeter, gram, and second, plus the electrostatic unit of charge (esu), defined as the charge that interacts with an equally large charge at a distance of 1 cm with a force of 1 dyne.
Electrostatics, not to mention static electricity, was not really something that fit into the sophisticated electronics world.

 Wolfson Electrostatics
Under the continued scrutiny of the television camera, a practice table was prepared and one of the most well-known of the top players, John Parrott, shot the cue ball several times, covering a range of velocities and spins, in attempts to produce kicks of the cue or object ball.
However, all the electrostatic potentials measured on the balls, the baize and John were no greater than 3 kilovolts, small in electrostatic terms.
We in Wolfson Electrostatics believe that kicks should be identified, reproduced and then examined under test conditions involving top players, electrostatic instrumentation and high-speed photography (to see if my pet theory has any merit).

 Industrial Electrostatics Demonstrations from the University of Rochester
The fundamental principles of electrostatics were all laboratory discoveries.
Though electrostatics is regarded by some as a science of mostly historic significance, many industries and commercial operations exploit electrostatic phenomena to achieve useful ends or are forced to dealt with electrostatic nuisances or hazards.
On the other hand, there are electrostatic nuisances which can slow production, affect product quality, or damage equipment, and of course incendiary electrical discharges which can cause fires or explosions leading to injury or death.

 ELECTROSTATICS NEWSLETTER
Many manufacturing processes involve electrostatics on the meter to centimeter scale.  At the other end of the size spectrum, the perfection of electrophotography as a method of document reproduction has required the application of electrostatic principles on a “tens-to-one micron” scale.
Recent work in micro-electromechanical systems has demonstrated the importance of electrostatics on a micron to sub-micron scale, and the rapidly emerging science of nanotechnology is pushing the size scale to well below the sub-micron limit.
We know far less than we would like to think about electrostatics and charge in general.  In a rush to electrodynamics in the mid 1800's, electrostatics was relegated to the parlor trick category it had occupied prior to that time.

 Static Electricity Static Control explanation and techniques to control the phenomenon of static electricity and how to ...
If the static charge is negative in polarity, the electrostatic field is negative and positive ions are generated via the grounded sharp ends of the induction device and the positive ions are attracted back to the static laden surface.
When the material becomes neutralized, there is no longer electrostatic attraction and the material will cease to absorb ions.
For example, an ElectroStatics, Incorporated Model 9000 electrostatic locator meter will measure the amount of static electricity that is present and identify the polarity as either positive or negative.

 Electrostatics
It is important to note that electrostatics are not caused by friction as most people initially think.
Electrostatics and friction are related in that they both are products of adhesion, which is the chemical bond that we talked about earlier.
Rubbing materials together can increase the electrostatic charge because more surface area is being contacted, but friction itself has nothing to do with the charge.

You may be asked to predict the magnitude and direction of the electrostatic force acting between charges.
You might be asked to calculate the resulting acceleration of the charge (remember, gravity is accelerating it vertically and the force due to the electrostatic repulsion or electric field is accelerating it horizontally).
You might be asked to calculate a time for it to travel a known distance or to calculate how fast it is going at the end of a known distance (both of these require you to know the acceleration).
