The present invention relates to an alloy of copper having high conductivity and low resistivity. Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electric charge is the property of matter that causes it to experience a force when close to other electrically charged matter.
Conduction in metals must follow Ohm's Law, which states that the current is directly proportional to the electric field applied to the metal. The key variable in applying Ohm's Law is a metal's resistivity. Resistivity is the opposite of electrical conductivity, evaluating how strongly a metal opposes the flow of electric current. This is commonly measured across the opposite faces of a one-meter cube of material and described as an ohm meter (Ω⋅m). Resistivity is often represented by the Greek letter rho (ρ). Electrical conductivity, on the other hand, is commonly measured by Siemens per metre (S⋅m−1) and represented by the Greek letter sigma (σ). One Siemens is equal to the reciprocal of one ohm.
Metals in general have high electrical conductivity. This conductivity comes from the large number of delocalized electrons in the outer orbit which are free to move. The atoms of metal elements are characterized by the presence of valence electrons - electrons in the outer shell of an atom that are free to move about. It is these 'free electrons' that allow metals to conduct an electric current. Because valence electrons are free to move they can travel through the lattice that forms the physical structure of a metal. Under an electric field, free electrons move through the metal, passing an electric charge as they move. The transfer of energy is strongest when there is little resistance. The most effective con...

...netic, paramagnetic and ferromagnetic depending upon their behaviour in a magnetic field. The alloys so produced have improved magnetic properties, thus showing improved electromagnetic conductivity.
The following table gives a list of the no of free electrons and the corresponding resistivity and conductivity of the components of the alloy. Metals have ‘energy bands’ which are nothing but energy levels grouped together which have similar energies. The characteristic energy level up to which the electrons fill is called the Fermi level. Only electrons in energy levels near the Fermi level are free to move around since the electrons can easily jump among the partially occupied states in that region. In metals the presence of many energy levels near the Fermi level, provides many electrons which can move. This is what causes the high electronic conductivity in metals.
An electrode is a component of an electric circuit that connects the conventional wiring of the circuit to a conducting medium such as an electrolyte or a gas. The electrically positive electrode is called the anode and the negative electrode the cathode. If an anode and a cathode are placed in a solution of an electrolyte and a source of direct current is connected between them, the positive ions in the
Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals. For example, when thermite (a mixture of powdered iron oxide and aluminum) is heated, the aluminum rapidly removes the oxygen from the iron; the heat of the reaction is sufficient to melt the iron. This phenomenon is used in the thermite process for welding iron .
Metals contain a sea of electrons (which are negatively charged) and which flow throughout the metal. This is what allows electric current to flow so well in all metals. An electrode is a component of an electric circuit that connects the wiring of the circuit to a gas or electrolyte. A compound that conducts in a solution is called an electrolyte. The electrically positive electrode is called the anode and the negative electrode the cathode.
Finally, gold parallels my goals for the future. It is one of the most conductive metals, extremely well suited for carrying an electric current. I, too, aim to conduct another kind of electricity-political organization, by pursuing a degree in Political Science at Harvard.

The alkaline earth metals are an interesting group of elements that have many properties and uses in this world. To learn about them will help one learn more about the world around them. These metals are soft, shiny, silvery, and very reactive; although they are not as reactive as the alkali metals, the group of elements right next to them. Speaking of groups, the alkaline earth metals are in the left side and in group 2 of the periodic table. When forming ions, the alkaline metals usually lose 2 electrons to get a positive 2 charge and become more stable. This allows them to take part in ionic bonds, mostly with the halogen family because halogens are negatively charged in their ionic form. Because the alkaline metals are positively charged, they attract and form ionic bonds.
Iron comes from the Latin word ferrum. The iron’s symbol on the periodic table is “Fe”, driven from its Latin name. Iron has an atomic number 26, and an atomic weight of 55.847. Iron is a metal that is grayish metallic and magnetic. This element is classified as a transition element because it is both malleable and ductile, and it can also conduct heat and electricity. Iron, cobalt and nickel are the only elements in the transition metals family known to produce a magnetic field.

A resistor is a passive two-terminal electrical component that implements electrical resistance as acircuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. Resistors are having fixed resistances or different resistances, which are found in thermistors, trimmers, photo resistors and potentiometers. The current through a resistor is directly proportional to the voltage across the resistor's terminals. This relationship is represented by
Mechanism : The metal which is higher in electrochemical series forms the anode and the metal which is lower in electrochemical series forms the cathode. The difference in electrochemical potentials of the 2 metals generates a potential difference between them. The potential difference between two dissimilar metals is the driving force for the destructive attack on the active metal (anode). Current flows through the electrolyte to the more noble metal (cathode) and the less noble (anode) metal will corrode. The conductivity of electrolyte will also affect the degree of
Selecting the right alloy for a given application entails considerations of its tensile strength, density, ductility, formability, workability, weldability, and corrosion resistance, to name a few. Aluminium alloys are used extensively in aircraft due to their high strength-to-weight ratio. On the other hand, pure aluminium metal is much too soft for such uses, and it does not have the high tensile strength that is needed for airplanes and helicopters. Because of its high conductivity and relatively low price compared with copper in the 1960s, aluminium was introduced at that time for household electrical wiring in North America. But the new use brought some
All metals can corrode but the speed of corrosion is different from a metal to another. Pure iron, corrode quickly while stainless steel which has iron and other alloys in its structure is slower to corrode and that’s why used more frequently. While other metals such as copper, silver, platinum and gold never corrode.
