In this episode of “EC&M Tech Talks,” Randy Barnett, a journeyman electrician, inspector, author, trainer, and electrical safety expert, takes a typically dry topic — electrical theory — and reviews ...

As we said last month, electrical theory underlies everything we do in the electrical construction business. It is therefore necessary to review this theory regularly. We continue now with Ohm's Law.

It is critical for technicians to have a solid understanding of electrical fundamentals. This foundation enables them to develop a systematic and methodical approach to troubleshooting, which will ...

ELECTRICAL theory, the most rapidly growing part of physics, has now reached such dimensions that no author can hope to produce a text-book which will deal effectively with its many aspects. A series ...

A WORK on electricity and magnetism which, starting from the differential equations of the electromagnetic field, works backwards to the experimental phenomena, cannot well be used as a text-book by ...
