Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...

If two dissimilar metals are touching and an external conducting path exists, corrosion of one the metals can take place.  Moisture or other materials...

This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...

When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...

We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
