Electret microphone: how does it work?
The electret microphone is very used in electronic projects, due to its low cost, size, good sensitivity, and mechanical resistance.
Circuit analysis with op-amp (Part 1)
This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
Operational amplifier: how does it work?
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
Fly-by-Wire: what is it?
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.
Electrolytic capacitor: how it works?
Why does the electrolytic capacitor has polarity? Why there is a voltage limit? These and other questions are answered in this post.
Geiger-Müller counter: how does it work?
This post’s subject is Geiger-Müller counter. An instrument invented in 1908, which identifies radioactive objects and measures ionizing radiation level.
Hysteresis: what is it?
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.
pHmeter: how does it work?
Meeting requests, today’s subject is the operation of pHmeter. An instrument that measures acidity and alkalinity of solutions.
MOSFET: how does it work?
The MOSFET is another type of field effect transistor. Much more used than JFET and it’s the most important component for digital computers.
