Statistical Electricity: Control, How To Work, And Examples In Daily Life

YOGYAKARTA - Static electricity is a physical phenomenon that emerges when electrically charged objects rub each other, so that one of the objects loses electrons and the other receives electrons. As a result, objects that lose positively charged electrons, while objects that receive negatively charged electrons.

The phenomenon of static electricity can easily be felt in everyday life, for example when we touch the door handle and feel a small sting. This happens because our bodies have collected electric loads, which then move to metal objects when in touch.

Static electricity is the result of the accumulation of electrical charges when stationary electric charges (statics) interact with each other (swimming). When two objects friction, part of the electrons move from one object to another, resulting in differences in electric charge which causes attractive or repulsive force interactions.

The way static electricity works starts from the process of electron displacement due to friction, conduction, or induction. Friction causes one object to lose electrons and another object to get it, such as in the example of glass and silk fabrics.

In conduction, charged objects come into direct contact with neutral objects so that the charge moves. Meanwhile, induction, charged objects are brought closer to neutral objects without direct contact, separating positive and negative charges inside the conductor.

The style interaction between two electrically charged objects is described in the Coulomb Law. According to this law, the magnitude of the attractive or repulsive force between two electrically charged objects is directly proportional to the magnitude of the load and is inversely proportional to the square of the distance between the two. This means that the larger the electric charge or the closer it is, the larger the interaction style that is produced will also be.

We can find static electrical phenomena in various daily events. The most common example is when combing hair and standing hair following the comb movement due to electrical interaction.

Another example is lightning, which occurs due to the displacement of electrons between clouds and the earth due to differences in electrical load. In addition, sneering the plastic ruler on a protective cloth or getting closer to the newly turned off television screen can also have a static electric effect.

In the human body, static electricity plays an important role in the nervous system. Electric signals in neurons are used to send messages between parts of the body. Certain animals, such as electric sickles and electric paries, are even able to produce or feel the electricity to survive and hunt prey.

The use of static electricity in modern technology is also very broad. One of them is in the process of painting the car. Electrically charged fine paint particles will be attracted to the surface of oppositely charged vehicles, thus producing a layer of paint that is even and neat.

The same principle is also used on the Inkjet printer, where small ink droplets are arranged with an electrostatic style to fall right on the desired position on paper. In addition, the photocopy machine also works based on the principle of static electricity.

In the photocopying machine, the photoconductor plate is given the induction load, then the light from the document to be copied. The electric charge on the plate then pulls the counter-charged ink, so that the print is in accordance with the original document.

From the explanation above, it can be concluded that static electricity is not just a simple phenomenon that causes hair to stand or small stings when touching metals, but a basic concept in physics that has various important applications in everyday life.
