RCDD 12th Edition Chapter 1 EXAM REVIEW [100% CORRECT]

RCDD 12th Edition Chapter 1 EXAM REVIEW [100% CORRECT] Elementry knowledge of transmission = *Ans* Electronics, electrical concepts, volts, AMP's and ohm's. An electrical conductor is = *Ans* Any material that can carry a electric charge from one point to another. Common conductors are = *Ans* Copper, Copper-covered steel, High strength alloys, Aluminum. Silver and gold are good conductors BUT = *Ans* Cost too much. Annealed copper = *Ans* 100% Alloying = *Ans* Adverse effect corrosion resistance = *Ans* High-strength alloys = poor Oxidation resistance = *Ans* Aluminum = poor Advantages of solid conductors = *Ans* - Less costly -[less complex termination systems] - Better transmission performance at high frequencies. Advantages of stranded conductors = *Ans* - More flexible -[Longer flex life] - Less susceptible to damage during crimp termination process. Not advantage of stranded = *Ans* Better transmission AWG = *Ans* Accepted in North America AWG in power distribution = *Ans* World wide Insulation/dielectric used to isolate current by preventing direct contact between = *Ans* - Conductors - A conductor and its environment Lower dielectric constant and dissipation factor = *A
