electrical system grounding: New Conductivity Concept
- 02/09/13 08:48 PM
As elementary school children we learn in science class the basic electrical principals of conductors and insulators. The strands of wire used in class show this concept in practice. The copper wire conductor is wrapped in a plastic insulator. The same is found in our homes, conductive wires wrapped in an insulating material of either cloth or plastic.
As adults we understand this fundamental electrical law. We know that sticking a fork into an outlet will give us a electrified wallop we won't soon forget.
If that fork is metal. A plastic fork will yield not the tiniest slap.
Another fundamental, … (20 comments)
