Introduction This article will present the different physical quantities that can be encountered in the electrical domain. First of all, we present the most common electrical quantities by giving a table that summarizes all the different parameters associated with their unit, symbol,...

Introduction When engineers design electronic circuits, they keep track of many different parameters, but one of the most important is power. In a modern circuit, the power evolves during its many stages, and sometimes it needs to be increased with amplifiers due to much loss caused by...

Most vacuum tubes need about 6.3V high supply plus filament voltage to operate. Running at 3.3V inclusively of the filament voltage, the new vacuum tube amplifier from Albert van Dalen has proven it possible to have one with the capacity to operate on an entirely low power supply...

Introduction This tutorial is a continuity of our last article about Thevenin's theorem. In the previous article, we have seen that any linear electrical circuit can be simplified into an elementary circuit that consists of an ideal voltage source in series with resistors. Another...

Axiomtek - a world-renowned leader relentlessly devoted in the research, development and manufacture of series of innovative and reliable industrial computer products of high efficiency – is pleased to announce the eBOX640-521-FL, its new high-performance fanless embedded system...

CircuitPython is a branch of MicroPhython designed to simplify education and experimentation on low-cost microcontrollers to make it easy to prototype without any upfront desktop software downloads. With CircuitPython, you can write clean and simple Python code to control your hardware...

ESP32-S2 WiFi SoC by Espressif Systems was first unveiled in May last year before its first internal development boards and datasheet were later showcased sometime in September but since the outbreak of the Coronavirus epidemic, progress on the board has really gone down the lane....

Introduction As we have seen in the previous tutorial presenting the fundamental laws of circuit analysis, Kirchoff's Circuit Laws (KCL) are a powerful and efficient tool to compute unknown voltages and currents in any circuit. However, KCL sometimes presents the inconvenience to be...
