At room temperature, graphene has slightly better conductivity than silver. Gold-plated will not corrode or tarnish like silver, but it generally is warmer sounding with rolled off or soft high frequencies. For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity. This tiny amount means that silver cannot resist the flow of electrons very well. It tends to push the upper mids and highs. Answer: C . Silver Conductivity “Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). How thick would you make the silver plating? B. Both A and R are true but R is NOT the correct explanation of A. C. A is true but R is false. Because resistivity is also inversely proportional to the conductivity of a substance, silver is an excellent conductor. Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: "shiny" or "white") and atomic number 47. A is true but R is false. Because it is the best thermal and electrical conductor of all the metals, silver is ideal for electrical applications. Silver is a very good conductor but expensive. Zinc makes up the other part of the alloy and degrades its electric performance. D. A is false but R is true. Suppose you have designed a microwave experiment to operate at a frequency of 1010 Hz. Sometimes there is a lack of bass or a lean bass. Reason (R) : Silver is a bad conductor. Silver also has the highest thermal conductivity of any element and the highest light reflectance. 2)Silver - it is the best conductor of electricity but is expensive so it is very rarely used for wiring 3)Gold - does not rust, is expensive and only used when high quality contacts are needed 4)Aluminium - not a good conductor but not as heavy as copper Silver has a large number of movable atoms which makes it a fine conductor. One of its component metals is copper, which is only second best to silver in electric conductivity. However, graphene is a 2-dimensional conductor, and does not conduct well between the graphene layers. In other words, a good conductor possesses a higher amount of free electrons which allow easy movement of electrons in … Option: A. Silver sulfide is not a conductor, but a semiconductor. Its high luster and reflectivity make it perfect for jewelry, silverware, and mirrors. Copper and Silver. They are one of the most common and best conductor of electricity. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Both A and R are true and R is the correct explanation of A. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance. Although it is considered to be a good electric conductor, brass is only 28 percent as conductive as copper. Thus the idea that the silver tarnish does not affect the connection is a bad myth. Silver is the best conductor of electricity. Its antimicrobial, non-toxic qualities make it useful in medicine and consumer products. Silver aggressively reacts with hydrogen sulfide, a gas that naturally occurs in the natural gas and also comes from cooking eggs (even fresh) and from the car exhaust. The resistivity of silver is about 1.59 × 10 −8 Ωm at 20 degrees Celsius. E. Both A and R are false. "Better" can mean many things: In terms of cost, aluminium is "better" than silver, and silver is better than graphene - if you want to make a wires of a given resistance.
