Static Electricity

Hello everyone, well currently New Zealand is on lockdown again cause of a new virus called Delta. So every student will be working from home, again. For this blog, in Science, we are moving on to a new topic called Static Electricity. It might sound a bit familiar to some people, but I'm getting excited to know more about electricity and I will also be learning about new things such as electrons and protons. Electricity is a form of energy produced by the presence of charged particles ( such as electrons and protons ), either statically as a charge accumulation or, dynamically as a current. For this topic, we have a new task and that is to answer these 4 questions.

1. What are the 3 particles that makeup everything? Which ones have positive and negative charges?

Atoms are the building blocks of all physical objects. Protons, electrons, and neutrons make up an atom. Protons have a positive charge -the nucleus is located in the center of each atom. Negatively charged electrons orbit the atom's nucleus. When energized protons pass close to orbiting electrons, their positive charge attracts the negatively charged electrons, causing them to fall out of their orbits. Electrons have a negative charge - electrons are subatomic particles that orbit an atom's nucleus. They usually have a negative charge and are significantly smaller than the atoms' nucleus. While neutrons are neutral. As a result, everything is made up of charges. Charges that are opposite each other attract each other (negative to positive). chares that are similar repel each other ( positive to positive or negative to negative). The majority of the time, positive and negative changes in an object are balanced, making it neutral. The effect of an imbalance between negative and positive charges in an object is static electricity. Certain materials can transfer negative charges, or electrons, by rubbing against one another. For example, rubbing your shoe on the carpet causes your body to collect extra electrons. Electrons cling to your body until they are freed.

2. Objects want to be “electrically neutral”. What does this mean?

A proton and an electron both have the same amount of charge, but they have the opposite type of charges. As a result, an atom is said to be electrically neutral if it has an equal number of protons and electrons.

3. When you rub two insulators you can get a static shock, so what is an insulator and a conductor?

Conductors are materials that allow electrons to easily flow from one particle to the next. When an object is formed of conducting material, the charge can be transferred across its whole surface. If a charge is applied to an object at a specific spot, the charge is swiftly dispersed across the object's whole surface. The movement of electrons causes charge dispersion.

Due to the ability f conductors to transmit electrons from one particle to another, a charged item will always spread its charge until the overall repulsive interactions between surplus electrons and minimized. When a charged conductor comes into contact with another object, it can transfer its charge to that thing. The transmission of charge between is facilitated if the second object is charged.

On the other hand, insulators are materials that prevent electrons from freely flowing from one atom to the next and from one molecule to the next. If the excess charge is transmitted to an insulator at a specific place, the surplus charge remains at the charging point. Because the insulator's particles prevent dispersed evenly across the insulator's surface. Electrostatic testing and demonstrations play an important part in insulation systems yet they are not useful for transferring charges. Leading objects are commonly attached to isolated items. This placement of a driver about the isolator inhibits the transfer of loads from the conductive objects to the environment. This arrangement can also be used to handle an object without touching it by a pupil (or teacher ).

4. What is an example of static electricity?

For example, electrons may be transferred from one material to the other when two different materials come into close contacts, such as rubbing a balloon on your hair, or two air masses in a storm cloud. When this occurs, one material gains an excess of electrons and becomes negatively charged, while the other gains an electron deficiency and becomes positively charged. The accumulation of imbalanced charges on objects causes a phenomenon known as static electricity. Also some other examples of static electricity that might happen to you, such as receiving shocks after shuffling across a carpet, taking clothes that cling to each other out of the dryer, etc.
