If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Electronics-loving orthodontic clinician Dr. Mark Brickley has developed a collection of electronic circuit-building experiments, tested them on unsuspecting colleagues, and then squeezed them into a ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components were ...

Engineers have shown that something as simple as the flow of air through open-cell foam can be used to perform digital computation, analog sensing and combined digital-analog control in soft ...

Consumer electronics that we use daily – smartphones, computers, televisions, home appliances and medical devices, as well as electronics in cars – all require printed circuit boards, or PCBs, to ...
