Why is it necessary to have an earth wire installed in a power circuit, but not in a lightening circuit? Why do you use a coil in a magnetic field? Explain why copper wire is a good conductor of electricity. Why does the needle of tangent galvanometer move with increasing or decreasing...
Why is an energy source needed in order to have a working electric circuit? Why can't all materials become superconductors? Explain why copper wire is a good conductor of electricity. Why were electrons chosen to be negatively charged? Wouldn't it make more sense to call electrons positively ...
The poor adhesion of copper to the copper oxide formed when copper is baked in air at high temperatures results in poor adhesion of the Teflon™ industrial coatings. Because of reactivity at the high baking temperatures, Teflon™ coatings have relatively poor adhesion to magnesium and to ...
Copper is naturally compatible with itself. Because copper is used to wire homes, by default it is also used in most appliances and electrical equipment. Copper is not compatible with other metals, such as aluminum. If the two metals are joined, a galvanic action can occur, and corrosion can...
Fiber optic cable is much thinner and lighter than copper cable. It can be used more efficiently in confined underground pipes, and is also much stronger, with eight times the pulling tension of copper wire. Furthermore, it has strength members and stiffeners that make it much ha...
This can be used for simple data exchange between devices. Resonant Coupling and Data: Some wireless power transfer technologies, like resonant inductive coupling, can, in theory, be used to transfer data alongside power. However, this application is rare and requires more advanced engineering and...
Also, conduits can be used to route electrical wiring, such as in commercial and residential buildings. Conduits are often made from PVC plastic, galvanized steel, aluminum or copper. All of these metals are good conductors of electricity and will not allow the electric current to flow through ...
