Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

Connecting them at only one point. Cutting the ground plane under a mixed signal component Connecting them with capacitors. Segmenting the ground plane in a PCB such that there is only a narrow ...

Here's what to look for, and how to fix what you find. Working on your own home is empowering, and it saves you money. Even ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

Researchers at Purdue University and the University of Virginia are now able to create “tiny, thin-film electronic circuits peelable from a surface,” the first step in creating an unobtrusive Internet ...
