In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.
In order for current to flow, it is not necessary for one charged particle to travel from the machine producing the current to that consuming it. Instead, the charged particle simply needs to nudge its neighbor a finite amount who will nudge its neighbor and on and on until a particle is nudged into the consumer, thus powering the machine. Essentially what is occurring here is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorously. This momentum transfer model makes metal an ideal choice for a conductor as metals, characteristically, possess a delocalized sea of electrons which gifts the electrons enough mobility to collide and thus effect a momentum transfer.
As discussed above, electrons are the primary mover in metals; however, other devices such the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell rely on positive charge carriers. Insulators are non-conducting materials with few mobile charges that support only insignificant electric currents.
American literature is based off of latin, greek, and other writings. From what i know, the byzantines had preserved the greek literature which we now use in today times for schools, colleges, and many other things as in jobs with engineering or teaching.
"The Bundle of Sticks," and "Hofus the Stonecutter" are two stories that show men who are dissatisfied with what is happening in their environment and decide to improve them.
The father in "The Bundle of Sticks," is totally dissatisfied with his kids fighting all the time. So he decides to show them why they should stick together and not fight anymore. This father doesn't want riches, or to change his life completely, he just wants peace to reign in his home and unity prevail among his children, because that will do them good.
In contrast, Hofus in "Hofus the Stonecutter" is so dissatisfied with his life that he wants to completely change who he is, which he does several times, but never gets satisfaction. Hofus always thinks that the life of another being is better than his, but after becoming several different beings he realizes that there is nothing better than being himself.
We can see that the main difference between these two men is how they brought about changes in their lives. The father in "The Bundle of Sticks," brought about a change in the world around him, but remained true to what he believes in, reaching satisfaction. Hofus in "Hofus the Stonecutter" was totally unfaithful to himself and although he had every wish fulfilled, he was unable to satisfy himself.
B. Is the answer to the question
