This code was created in 2001-2004 when I taught Borland Delphi 3 to myself. It contains many, many global variables, unstructured and undocumented procedural code and bad variable names. If you don’t ...

What if electronic circuits could be created simply by drawing lines with a pencil on paper or leaves—and then immediately ...

What if circuits could be drawn like pencil marks, work on almost any surface, and then be erased and reused when no longer ...

Article 210 contains the requirements for conductor sizing, conductor identification, overcurrent protection, and GFCI and AFCI protection of branch circuits. It also contains requirements for ...

A branch circuit consists of the conductors between the final overcurrent protection device (OCPD) and the point of use outlets [Art. 100] (Fig. 1). Article 210 ...

When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be a ...

In the comment section of my last article, there was some great discussion about drawing schematic symbols. It is important you make your schematic symbols understandable. Sometimes, the pre-packaged ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

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 ...

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 ...
