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 ...

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 ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

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 ...

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 ...

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 ...

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 ...
