The science contained in portable charger

over 1 year ago

Greetings reader friend back with more science, for this occasion taking a simple in a portable power bank, which is for daily use, for today I share all the information at the level of science and technology, one of the things that It helps us to be connected and share information with our cell phone if it has a good battery, but for today, they have developed a portable charging device, which gives us a lot of comfort and confidence, which is what makes this charging device unique. , good my reader friends, since we have as a starting point with the need and charge requirement of our cell phone, where it has been shown that the capacity of cell phone batteries is measured in milliamps (aMh), its requirement They oscillate at 3 thousand mAh to complete their charge, since with the technology standards in portable charging devices, they have an amp input and output feature that the power bank must have is 2.4 mAh.

Now, for my case, my charging device is 10,000 mAh, with two USB ports, one type C, as we can see, its positive and negative cable is red and black, we can also distinguish two laminated flattened batteries , is a lithium battery controlled by a microchip that we can also see, so that it detects the connected device and supplies it with the necessary current that said device supports, thanks to the fact that it has protection circuits against overcurrent and short circuit, the most recommended are I design that it has the characteristic of 10000 mAh(10 Ah) to 20000 mAh(20Ah), as a reference of charging hours and also has the singularity of Input: 5V/2A, Output: 5.1V/2.1A.

What is interesting about this type of technology shows us at the level of physics the behavior of charge and electric current, where the most basic thing is to know that only electric current is the flow of these moving charges through the conductor, but not everything ends here since my reader friends too, you should know that there needs to be a conductor, which applies an electric field, where the charges experience a force and therefore are in motion, after this point It is appropriate to mention again the intensity of electric current (I), this allows us to define it as the amount of electric charge (Q), measured in Coulombs, because in most cases it is considered that it crosses a section of a conductor in each unit of time, since all this is representation is a scalar magnitude. Fascinating as this small device also shows us, the behavior of the electric charge, taking into account that it is in movement in the conductor under the action of the electric field, since it represents them are the free electrons experiencing a phenomenon of a given force, On the other hand, as a basic foundation, the unit of electric current in the International System is the Ampere (A). something singular is that when tensions are evidenced in the negative and positive poles we have that, the electric current is defined by convention in the opposite direction to the displacement of the electrons, which simplifies it to two types of electric charges:

(+) Positive charge: Corresponds to the charge of the proton.

(-) Negative charge: Corresponds to the charge of the electron.

Continuing in our order of ideas we have how fascinating is the type of circuit, that this type of mobile charging device has, which helps us in our life for charging, phones and any other device for charging, with this recommended type of mAh, now well 1 Coulomb = 6.25x10 ^18 electrons, and un1A = 1 C/s, where also in case of representing a force vector, which acts on the electrons has the opposite direction to that of the electric field vector, Lastly we have, as several friends mentioned to me, what happens when the bacterium of this device swells or dilates, a swollen battery is that the lithium turns into gas and that this gas combusts, if it comes into contact with oxygen (O2 ), an explosive reaction occurs, thanks to the fact that it is the result of the particles being trapped between the layers of the battery and eventually perforating the membrane that separates them, it is recommended to isolate the bacteria and not use it anymore, because it has already lost its life to useful, either due to overload, misuse of the device when loading another with other standards.
