Even if the total current exceeds 15A when multiple electronic appliances are used from one outlet, the safety breaker will not trip as long as the current does not exceed 20A, but if you continue to use them like this for a long time, the outlet or plug will get hot, which is dangerous!

So let's try to close in on the true nature of electricity!

An electron in the outermost shell is called a valence electron. A valence electron easily becomes a free electron because the binding force of the atom is the weakest in the outermost electron shell.

I get it!

Let's talk about static electricity in a little more detail.

Static electricity that is generated by friction in this way is also called frictional electricity or triboelectricity.

If something that is not charged approaches something that is charged, it becomes charged too. It's a phenomenon called electrostatic induction. 

Static electricity is more easily generated when the air is dry - like in winter, when the humidity level is low.

Thanks to you, I have a pretty good understanding of it.

Current is the quantity of electricity flowing per second through an electric line, and it is represented using the symbol I, which comes from the initial letter of Intensity of electricity. Current is measured in amperes (A), or amps for short. One amp is equal to one coulomb per second.

A watt-second (Ws) is equivalent to a joule (J).

Electrons move around the nucleus in a series of orbits called electron shells. Since the attraction from the nucleus is weaker for electrons in the outermost shells than ones in the innermost shells, electrons in those outermost shells may escape from orbit if external energy such as heat or light is applied. An electron that has escaped from orbit can move around freely and is called a free electron. The outermost electron shell of an atom is called the valence shell, and the electrons that are in it are called valence electrons. 

Since static electricity is generated by friction, it is also called frictional electricity.

The size of the electrostatic force (also known as Coulomb's force) of attraction or repulsion operating between charge Q1 and Q2 is directly proportional to the product of Q1 and Q2 and inversely proportional to the square of the distance between the charges. This is called Coulomb's law with respect to static electricity.

A phenomenon, in which something that is not charged becomes charged when it is in close proximity to something else that is charged, is called electrostatic induction.

Static electricity is more easily generated as the air gets drier - humidity prevents static electricity from gathering on a surface.

The polarities of the charges that are generated by friction differ according to the materials that are rubbed together. These differences are represented by the triboelectric series.

You can reduce the occurrence of static electricity by wearing clothes that are made of materials that are close together in the triboelectric series.

The current can be obtained by dividing the charge by the time.

The speed at which the electrons move is very slow - less than 1 cm per second. However, the speed at which electrical motion is transmitted to neighboring electrons is the same as the speed of light: 300,000 km per second. Therefore, the current also flows at 300,000 km per second (the speed of light).
