Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...

When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

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 ...

Do you think your computer is fast enough? Think again. The computers of the future could work almost at the speed of light! Nanophotonics, the study of light at the nanometer scale, could indeed ...

Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...

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 ...

Electrical engineers have long been toying with the idea of designing biological molecules that can be directly integrated into electronic circuits. Researchers have developed a way to form these ...

It's only a circuit breaker. How hard could it be? A surprising number of engineers specify the wrong type of circuit breaker to protect their equipment. Engineers frequently overprotect or ...

Branch circuits are undoubtedly the most commonly installed circuits in both residential and non-residential applications. And, since they supply the equipment that utilizes the electricity, they are ...

According to the most recent data from the World Bank, 15 percent of the world’s population—approximately 1.1 billion people—lacked access to electricity in 2014. In 1994, approximately 27 percent of ...
