Platinum will almost always be more expensive than white gold because it is 30 times more rare and mined much less than gold. To be more specific, 2,700 tons of gold are mined per year compared to 80 tons of platinum. Also, platinum is denser than gold.

Below is a list of all of the known elements, who they were discovered by and the year they were discovered….Questions and Answers.

Gold gets its name from the Anglo-Saxon word “geolo” for yellow. The symbol Au comes from the Latin word for gold, “aurum.”

Many people in California figured gold was there, but it was James W. Marshall on January 24, 1848, who saw something shiny in Sutter Creek near Coloma, California. He had discovered gold unexpectedly while overseeing construction of a sawmill on the American River.

The lowest rates in continental Europe are in Switzerland, where VAT on silver is 8%. At today’s prices, that will add about $1.50 to each one-ounce silver coin… a little less than the low premium over spot you’d pay to an online dealer in the US, or from our friends in Singapore where your silver is stored for free.

Silver bars can be purchased from major banks as well as bullion dealers. “The bullion coins can be purchased through the U.S. Mint as well as through authorized dealers, while the collector coins can be purchased through collectors and private sellers.”

Silver bars and ingots Coins often trade for prices several percentage points above the spot price, but you can buy silver bars for pennies above spot. A typical silver bar being sold at spot often isn’t very artistic, but gram-for-gram it is one of the cheapest methods for buying silver.

Just as you might sell gold or platinum, you can sell silver in a number of ways. The most common of these is to bring your silver to a pawn shop, a silver exchange, consignment shop, a local jeweler, or by using an online website.

Physical gold and silver prices are based on the floating “spot price” of the respective metals. That is, they are the easiest to sell at the best prices. These include products like the gold & silver American Eagles and Canadian Maple Leafs. Often there is a correlation between premium and liquidity.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color.

Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Copper and its alloys are also used to make electrical contacts.

Among the common types of copper wire are: Beryllium Copper wire. Copper Alloy wire. Copper Clad Aluminum wire.

Most of the products of Copper Wires ranges from Rs 500 to Rs 750 per Kg. Price varies according to Wire guage, Size and material of Copper Wires….Questions & Answers on Copper Wires.

Copper is used for electrical wiringbecause it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.

Copper is a good conductor of electricity that allows the electricity to flow through it easily. So it is used to make connecting wires.

Answer: The main reasons are cost/availability, workability, resilience in the field. Copper is relatively abundant and has very good conductive and thermal properties.

Copper is a far better conductor than graphite and is universally used for making wires. Graphite is more resistive and a poorer conductor.

Unlike silver which in its natural state is a metal like copper, the form of graphite with very low resistivity to compare with copper is graphene. Technically its not a metal which can be extruded into wires but a few atoms thick crystallene structure that would be difficult to manufacture and use for wiring.

Most electrical wire is covered in a rubber or plastic coating called insulation. The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors.

Copper wires are usually covered with rubber or plastics to prevent shocks and ensure safety. Because plastics and rubbers are insulators of electricity i.e. they cannot conduct electricity.

Duct tape is a multi-purpose utility product and is NOT a suitable electrical tape substitute where electricity is concerned. Duct tape, or any other kind of adhesive tape for that matter, will not do the job safely.

conductors

Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity.

Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors.

Well actually, pure water is an excellent insulator and does not conduct electricity. The thing is, you won’t find any pure water in nature, so don’t mix electricity and water.

Most metals are pretty good conductors; however, apart from silver, copper is the best….

Tungsten is a metal which is a bad conductor of heat and electricity.
