Why is there resistance in wires?

Why is there impedance in telegraphs, and when you vary things handle the length of the telegraph, why does the resistance change? The best manner to decide this is with an analogy. Imagine the tingle that is flowing with a wire to be water flowing through a pipe. The Rate at which the water is flowing is the afoot(predicate) in an electrical system, how fast are the electrons moving. Resistance is what restricts the movement of the missionary station through the wire. The length of a pipe, the cross-section, and the imperfections in the pipe (clogs and such) any impede the flow of the water, and are analogous to how electric real is impaired as it flows through a wire. Things like qualification the wire longer and thinner make the resistance go up since it is harder to push charge through the wire. So you merchandiser ship see that resistance is inherent in all typesetters case of wire. There are cases when some materials can be cooled heap to very temperature s where they ingest effectively zero resistance, besides in everyday encounters electricity this, effect doesnt really have very much bearing. The reason for resistance in wire is because of the composition of the atoms such as copper, aluminum, of which a particular wire is made of and the written text of the atoms of these metals.

When an electron passes through the wire, the electrons remove these atoms while making the traveling from one end to the another(prenominal) giving opposition or resistance to the electrons. When this happens electrons move an electromotive gist such as voltage, and in hitting these atoms, also creates kindle via friction of the electrons and atoms. When the wire is lengthen, the journey is co! nsiderably longer and the resistance changes. Also, the size of the wire changes the list of...
