Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow make a light blink, produce music, and detect motion. So I was happy to ...

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and ...

Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

New “transient electronics” dissolve in the presence of water, opening up a new range of possible applications. Image via the Beckman Institute, University of Illinois and Tufts University For most of ...

If the power source is a listed Class 2 transformer or listed Class 2 power supply — or it’s in listed equipment marked to identify the Class 2 power source — you’ve got a Class 2 circuit between the ...

As with the clock, many compelling biological questions centre on how interactions among genes and proteins, forming genetic circuits, give rise to specific cellular functions. Genetic and biochemical ...
