Most every device and electronic piece of equipment is outfitted with a printed circuit board (PCB), including smartphones, TVs, appliances, and more. You know the composite. The boards are laminated ...

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

This video breaks down how resistors work and why they’re one of the most essential components in every electronic device.

This video provides a clear explanation of resistors and their role in electronic circuits. It introduces the principles ...

QSPICE is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and reliability. It is a new program and can be downloaded here. QSPICE is still in the demonstration ...

Based on CD4017 and logic gates this electronic circuit switches on a relay if you press four keys in the correct sequence, and backs to the start condition by pressing any key. Once the circuit is ...
