The electret microphone is very used in electronic projects, due to its low cost, size, good sensitivity, and mechanical resistance.
This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
This post’s subject is an introduction to Fly-by-Wire systems on modern airplanes. It’s shown how it works and the advantages in relation to old systems.
Why does the electrolytic capacitor has polarity? Why there is a voltage limit? These and other questions are answered in this post.
This post’s subject is Geiger-Müller counter. An instrument invented in 1908, which identifies radioactive objects and measures ionizing radiation level.
The hysteresis is very common on materials and systems. It’s the capacity to keep a property, after remove the stimulus that induces this property.
Meeting requests, today’s subject is the operation of pHmeter. An instrument that measures acidity and alkalinity of solutions.
The MOSFET is another type of field effect transistor. Much more used than JFET and it’s the most important component for digital computers.
The junction field effect transistor (FET) is a component with many applications. In this post, are shown the structure and the operation.
