Electronics for beginners. Here are collected interesting articles with the basics of electronics, theory, elements, their description. Using simple examples, you can understand how electronic components are arranged, how to check them and how they work: resistor, photoresistor, capacitor, diode, zener diode, IGBT transistor, mosfet. Letter designations in electrical circuits of the GOST standard and foreign IEEE. There is also a calculator for calculating the resistance by the color marking of the resistor, marking of smd resistors, marking of smd capacitors. Linear and switching voltage regulator. Varistors.
