Static Electricity

Electric charge in a stationary position, may evolve from a equilibrium that has lost its balanced base on positive and negative charges on a surface or within the surface. On a surface charges may build up until it has enough energy to move away from the electric current field and become combined with another service. The building up on charges on or within a system is known as Static Electricity [1]. For example is an hurricane is happening if the electric wire become expose while current is in flown in the line. another example is walking a cross the a door knob and receiving a shock as you touch the door knob which can be seen by clicking the link below .There are three ways in which charges can be generated namely: Induction, Contact and by Friction. The negative and positive charge exist on the smallest chemically balance substance called an atom. Atoms comprises of positively charged protons, neutral neutrons and negatively charged electrons. Most material that exist in nature has a balance amount of protons and neutrons these materials do not exhibit the property of static electricity until it becomes unbalanced. Though electrons are small in nature by the process on moving they may attach to another material allowing the material to increase in electrons significantly whilst leaving protons on a surface, this material become negatively charged. This results in a unbalanced system. Electrons due to the balance that exist in nature may attach to a negative charged material easy or attach it self to system that is unbalance and needs more electrons. The switch movement of electrons from one area of high concentration to the next is what results in STATIC ELECTRCITY. This phenomena does not happen with all object by object that good conductors such as metals and salt water. In contrast t substances like bottles and glass does not have loosely bounded electrons therefore they do not conduct electricity easily. Static electricity generally happens between conductors and insulators [1].

Atoms

May be defined as the smallest substance in which a matter can be divided without emitting charged electrical particles. This is the smallest particles of any material that contains all the attributes of a chemical element. Atoms are the basic foundation of all chemical substances. Atoms consist of protons, neutrons and electrons. Examples of substances that contains atoms are pencil, vehicles, television and phones. Atoms are extremely small they cannot be seen with visible eyes or microscope.

The three ways in which static electricity can be generated are friction, conduction and induction. A description of each method can be seen below.

Charging by Friction

Charging otherwise known as charging by contact requires two surface to touch in order for electricity to be generated. This involves the intentional rubbing of one material across another, with this electrons are moved from one location to other. This method is useful for charging insulators[6].

Charging by Conduction

This involves the charging of material with the use of a conductor. Charges move from a charged material to an conductor. Conductors are charged using this method[6].

Charging by Induction

This method is only charging method that requires and charging without any form of touching. Charged particles are held closely to conductive material that is uncharged in this state the particle is neutrally charged. A neutrally charged atom has the same number of protons (positively charged atoms) and electron (negatively charged atoms).The process of induction involves the charging of one body that does not loose any of its charges when it interacts with another, it only gains charges while another looses. The usage of the neutral and charge particle will result in a opposite polarity. A negative polarity makes reference to the uncharged object becoming more negatively charged due to the increase electrons that is attracted[6].

Benefits of Static Electricity

Three benefits of static electricity are [13]:

1. The Printing of Papers : During the coping process static electricity is useful. Xerography is the process by which coping of print to a page is done. Charges within the copier serves different purposes. Electrically charged ink within the system will adhere to the paper at selected regions (the regions that are darken).Another type of copier may allows charges to stick to the ink to the drum, which then transfer the ink to the paper.

2. Coating of Cars : In the coating of cars. Automolbile manufactuers depends heaily on static electricity to assist them in spraying or painting of echicles. After the surface of the car is prepared, the vechicle is placed in a paint booth. Paint is induced with electrical charge and a fine mist of paint sprayed into the booth. Enabiliting the charged particles of the paint to stick to the body of the vechicle. Similar to the cahrged ballon sticking to the wall. Whenever the paint dries on the wall it adheres to the car better, as the paint is more easily distributed.

3. Controlling Air Pollution :Static electricity is used to control air pollution. An electrostatic precipitator are devices that applies static charge to dirty particles in the atmosphere, charged particles that are attached to dirt in the atmosphere are collected by on a plate pr on a surface having   opposite electrical; charges, opposites attract.

Hazards of Static Electricity

Hazards of harmful impact of static electricity that may arise are [14]:

1. Damage to Organism or Infrastructure functionality :Due to the sharp nature of how charges emerge for one surface to the next, it may cause heart attacks, burns to the body or an object and  may cause an object of individual to fall due to the overload of charges attracted to there surface.

2. Damage or destruction of electrical device :Due to the electrostatic discharge (ESD) at one time by cause damage to electronic devices components of an electrostatic unit.

3. May cause fire :May cause fire if it interacts with environment or materials that are flammable in nature example phones or cars.
