Perhaps the most prominent topic in our questions section and about which we are consulted in conversations with our followers is the use of electrolytic capacitors. For many, it may seem like a simple capacitor, but it doesn't have such a simple behavior due to its characteristics. In this article, we approach the behavior of these capacitors in a slightly more profound way, thus removing doubts that many may have.

When we analyze the history of electronics, we usually sequence technologies with passive components, valves, transistors, and the era of integrated circuits overlooking quantum electronics. But isn't there anything missing in that sequence? That is what we will see in this article. We will travel to the past, to the time of valves, and discover that there was already a similar technology, which was somewhat forgotten, that of magnetic amplifiers.

The "zoology" of electronic components presents very interesting facts for readers who are interested in "archaeological studies" of this science. Not only what certain components did is interesting, many of which disappeared, but also the assigned names that followed a certain logic. We have already dealt with other articles on components ending in "tor" and we see that a large number of them have not reached our times. In this article we deal with components terminated in “tron”.

In the past, the only simple and most used way to store energy was through batteries. Batteries have evolved, allowing ever greater amounts of electrical energy to be stored, but at the same time new forms of energy storage have been created, improved and are now very promising, some with important practical applications. In this article, we focus on these technologies and with special attention to their application with forms of energy generation which also evolve day by day, such as solar and wind power.
