Electrostatics

Electrostatics is the branch of physics that deals with the study of charges at rest. A common electrostatic phenomena is plastic wrap sticking to your hand and itself when removed from the box. Everything to do with electrostatics goes in this category.

What are the positive uses of static electricity?

Some people purchase what are called air ionizers to freshen and purify the air in their homes. They work on a similar principle as the smokestack pollution control. These devices strip electrons from smoke molecules, dust particles, and pollen in the air, just as what happens in creating static electricity.

These charged dust and smoke particles are then attracted to and stick to a plate on the device with the opposite charge. After a while, much of the pollution is drawn from the air.

Since charged particles will also stick to neutral surfaces, some of them can stick to the wall near the ionizer, making it very dirty and difficult to clean.

Why didn't the US national debt from World War 2 cause hyperinflation?

America instituted many price and wage controls during World War II to hold down inflation. Rent control got its start during the war and employers starting offering benefits such as health insurance to bypass wage controls. Shortages did occur and life was quite tough for those back home during the war. Once the wage controls were released after the war, prices did increase significantly. Prices went up 37 percent from 1944 and 1948, about the equivalent of the increase from 1976 to 1980.

What is a device that detects electric charge?

It is called an electroscope.
A static electric charge can be detected directly by a device called an Ishmoo. It has a plate on top and a plate inside. The inside plate moves a mirror and it reflects a light slit onto the meter face and reads out static voltage. A standard electric voltage meter today, A VOM, would have an attenuator switch and read out digitally.

Why is static electricity not useful?

Because when you put clothes on they zap you. It can also cause great catastrophe. It can cause things to ignite. History shows many bad events due to static. etc the zeplin and many aviation related incidents.

How does an electric generator works?

The voltage was produce by cutting of the magnetic flux by the conductors.

How is static electricity used in the real world?

One example:

To reduce pollution from smoke stacks, or to purify air within households, companies/individuals use a filtration system called an electrostatic precipitator (ESP).

The system works by passing smoke through a grid of electrically charged rods. The particles in the smoke pick up a charge of Q. The smoke then travels through a series of plates that have a charge of -Q. Since opposite charges attract, the particles cling to the plates. The plates are then shaken so that the ash falls into a hopper that can be removed and discarded.

This process can reduce air pollution from a smoke stack by 99%.

What is a temporary indulgence?

Temporary Indulgence Temporary Indulgence is a grace period, usually 30 to 60 days, that may be granted to allow you to bring the mortgage current

Can build up as static electricity and can be discharged?

Static electricity occurs when there is a build-up of electric charge on the surface of an object. This build-up can be discharged through a spark or a sudden flow of current when the object comes into contact with another object with a different charge, such as another person or a metal surface.
