Electricity is all around us – our technology, such as cell phone, computer, light, solder iron and air conditioner. It is difficult to save it in our modern world. Even when you try to avoid electricity, even then it works perfectly, from the thunder of electricity to the inside of your body. But what is really electricity? This is a very complex question, and as you dig deeper and ask more questions, in reality, it has no definitive answer, how does electricity get power in our vicinity?

Electricity is a natural phenomenon which is in full form and occurs in many different forms. In this tutorial, we will focus on current electricity: the stuff that gives our electronic gadget power. Our goal is to understand how electricity drives our communication equipment with power sources, LED lights, spinning motors and electricity.

Electricity is briefly defined as the flow of electric charge, but there is much more behind that simple statement. Where do the allegations come from? How will we move them forward? Where is he going? An electric charge causes mechanical motion or makes things light? so many questions! To explain that for those atoms, we need to zoom in the kind of substances and molecules in contact with life.

The atom

To understand the fundamentals of electricity, we have to start by concentrating on atoms, one of the basic building blocks of life and substance. Atoms are present in more than one hundred different forms, such as chemical elements such as hydrogen, carbon, oxygen and copper. Many types of atoms can combine to form molecules, which create the case which we can physically see and touch.

Atoms are smaller, which are up to 300 o’clock. (Which is 3×10-10 or 0.0000000003 m) copper money (if it was actually made of 100% copper), then inside it was a 3.2×1022 atom (32 billion atoms), copper.

To understand that the work of atomic energy is not very small. We need to dive to the second level and see the construction blocks of atoms: protons, neutrons and electrons.

Construction blocks of atoms

An atom is made up of three different particles: electrons, protons and neutrons each atom have a central nucleus where protons and neutrons are packed together in a dense manner. A group of electrons revolve around the nucleus.

Rutherford atomic model

A very simple nuclear model. It does not understand how nuclear is made, it is not useful to understand. The main nucleus of protons and neutrons is surrounded by orbiting the electrons.

Every atom should have at least one proton. The number of protons in an atom is important because it defines which atom is represented by a chemical element. For example, atomic hydrogen with only one proton, an atomic copper with 29 protons and nuclear plutonium with 94 protons. This count of protons is called the atom’s atomic number.

Proton’s nucleus-partner, neutron, serves an important purpose; They keep the proton in the nucleus and determine the isotopic of an atom. They are not important for our understanding of electricity, so let’s not worry about this tutorial about them.

Electrons are important for the work of electricity (general subject information on their name?) In its most stable, balanced condition, the atom has the number of electrons similar to the proton. Under the Bohar nuclear model, with a 29 proton, a nucleus (by making copper atoms) is surrounded by equal electrons.

Copper Bohr model

As our understanding of atoms has evolved, we also have a method of modelling for them. Bohr model is a very useful nuclear model because we detect electricity.

Electrons of atoms are not always tied to atoms. The electrons present in the outer orbit of the atom are called the valence electrons. With enough external force, a valence electron can escape the orbit of the atom and may be free. Free electrons allow us to charge, what about electricity charges .

Flowing charging

As we mentioned at the beginning of this tutorial, electricity is defined as the flow of electric charge. The free content is a property – such as mass, quantity or density. It’s measurable. As you can determine how much mass is in an object, you can measure how much charge it has. The key concept with the charge is that it can come in two types: positive (+) or negative (-).
