∙ 13y agocopper is cheaper. silver does work better though.
Wiki User
∙ 11y agoBeacause copper conducts electricity very well
Wiki User
∙ 8y agoSilver can be used for making wires, but copper is significantly cheaper.
Wiki User
∙ 11y agoIt all has to do with the cost of the metal and the availability of the metal.

What materials make good electrical conductors?
Superconductors are materials that offer no electrical resistance whatsoever but the highest temperature any known superconductor can be while retaining its conductive properties is -181 degrees Celsius, making them an extremely impractical and expensive material for most purposes. As far as I know the most conductive material at room temperature is pure silver, which is slightly more conductive then pure copper and 50% more conductive then pure gold. Copper and gold are both used commonly for conduction however because copper is much cheaper then silver and nearly as conductive, and gold is more resistant to corrosion then either silver or copper despite its reduced capacity for electrical conduction.
What is meant by good conductors?
If a material allows free electrons to move easily from one atom to another then we call that material a conductor. Most metals let their free electrons roam, so most metals are good conductors. Silver is the best conductor. Copper is almost as good at conducting as silver, and it costs a lot less, so copper is the most popular material used in electrical pathways, or circuits.
How can chemical reactions produce color change?
Simply put, the products are a different color from the reactants. For example, when copper reacts with a silver nitrate solution it turns the solution from colorless to blue. This is because while the silver ions (Ag+) do not affect the solution while the copper ions (Cu2+) released by the reaction are blue in the presence of water.
Is copper more or less denser than water?
A cubic foot of Copper weighs 550 pounds and has a specific gravity of nearly 9. A cubic foot of Tin weighs 450 pounds and has a specific gravity of 7.29. So, Copper is more dense than Tin.
What is the use of eureka wire?
Eureka wire consists of Nickel 45% and Copper 55% . its operating temp. is 400 degreeC while melting point is 1270 degreeC.
How many nano ohms transferred per meter in copper?
Gold has an electrical resistance of 22.14 nano ohms per meter (nΩ·m), while copper has an electrical resistance of 17.2 nΩ/m and silver has an electrical resistance of 15.87 nΩ/m.
What out of copper gold and silver which is best suited for an electrical wire?
All three are very good conductors.Copper is relatively inexpensive, while gold and silver are very expensive.Copper and silver oxidize slowly to a conductive oxide, gold does not oxidize or corrodeConsidering the above copper is generally the best choice for electrical wire unless corrosion is a potentially serious problem, in which case a very thin gold plating on copper wire may be a reasonable choice.

What substance is formed on a copper metal surface while in a silver nitrate solution?
Copper Nitrate
What materials will conduct the flow of electricity?
While electricity doesn't flow, current does. Conductors are materials that allow the electrical currents to flow through them. Metals are the best conduction, such as silver and copper.
Copper will react with silver nitrate to form copper nitrate and silver?
In certain reaction conditions, yes. Copper is more reactive than silver, so it should react with the nitrate molecule to form copper nitrate while precipitating the silver. *Are you thinking about separating silver from photographic fixer? Commonly a less expensive metal is used like iron (steel wool) to extract much of the silver.
What metals are conductors?
The related link lists all of the elements of the Periodic Table, by electrical conductivity. The top of the list is the worst conductor (Sulfur). The most conductive is silver. The second most conductive metal is copper. Due to expense of silver, copper is preferred. Aluminum is commonly used due to weight factor and cost. (even though a thicker wire is necessary to carry the same current). Gold, while more expensive and less conductive than copper, is resistant to corrosion, and is very ductile.
What is a physical property shared by gold and copper but not iron?
while electrical conductivity is shared by Gold copper AND iron.. malleability is the property shared by gold and copper but not iron
What is a gem on fiesta online?
1 gem = 100 gold 1 gold = 1000 silver 1 silver = 1000 copper While 1,000 copper is 1 silver and 1,000 silver is 1 gold, it only takes 100 gold to make a gem.
Why is metal use for electricity?
Metal is used because metals conduct electric current. The best conductor among the metals is silver, followed by copper, then aluminium. Copper is used for electrical wiring in the house and for underground supplies, while the lightness of aluminium makes it the metal of choice for overhead power lines.
When did they stop making half dollars?
Kennedy half dollars are still minted for general circulation in Copper-Nickel Clad Copper for circulation while some Proofs (San Francisco Mint {S}) are made in Silver. Check with your favorite federal bank for one or in rolls.
