Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.

What metal is the best conductor of heat?
We know that silver is the best heat conductor among the metals, followed by copper.
What are conductOR of heat?
Most of the metals are effective conductors of heat.They conduct heat without much loss in energy and quickly.Copper, silver are among best conductors of heat.metals are good conductor of heat.
What naturally occurring substance is the best conductor of electricity?
Noble metals have the best conductivity of nature's elements. Among these, Gold, Platinum, Silver, and Copper are the best. Copper, being far less costly than the rest has come into common use in electrical wiring of all sorts, precisely for these reasons.
Can you pick up a silver dollar with a magnet?
Only certain metals have an atomic arrangement that causes them to be attracted to a magnet. Nickel, iron, and steel are among the most common. Copper, gold, and silver are not arranged in a way that causes them to be attracted. True silver dollars (1935 and before) are 90% silver and 10% copper so they do not contain any magnetic metal. Modern dollar coins (1971 and later) aren't silver, they're mostly copper with the rest being nickel or manganese. There's not enough nickel in them to be attracted to a magnet.
What is best conductor of heat among liquids?
mercury
What are examples of good conductors of heat?
In general, metals conduct heat well. Silver, copper, gold and aluminum are among the best. Oddly, carbon in its diamond allotrope is the best conductor of heat we know of.
What metal is the best conductor of heat?
We know that silver is the best heat conductor among the metals, followed by copper.
Which is the least conductor among iron copper aluminum?
Between iron, copper, and aluminum, copper is the best, followed by aluminum, and last by iron. Gold is often plated over other metals because it is even better and resists corrosion.
Why is copper good for electrical wiring?
Copper is an excellent conductor of electricity. Among metals it is second only o silver, which is too expensive for practical use in wiring. Copper is also extremely ductile, meaning it can be easily drawn into wires without breaking.
Is aluminum more conductive than copper?
Copper. Alloys of copper are used in most of the electrical wiring indoors and/or outdoors.However, aluminum is used in long-distance high-tension electrical lines because by weight it's a better conductor than copper is (and because it's less expensive and stronger). An aluminum wire needs to be thicker than a copper wire in order to have the same current-carrying capacity. However, even though it's thicker, it weighs less, which means the relatively expensive transmission towers can be spaced further apart without the wire sagging too much.
What metals can be found in an iPhone?
Aluminium
Is gold a good conduct of gold?
It does conduct fairly well, but it's not among the very best conductors. One reason that connectors are sometimes plated with gold is that while gold isn't as good a conductor as, say, copper or silver, unlike those metals gold doesn't tarnish, and gold is a much better conductor than copper or silver oxide.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
What type of metal will conduct electricity the best?
Silver has the highest electrical conductivity of any metal, followed closely by copper, gold, and aluminum.It should be noted that electrical conductivity is a function of temperature and all comparisons must be made at a standard temperature or adjusted for temperature.Answer:The name of the metals are on the left and the conductivity level on the right...[units appear to be 1/(ohm-m)]Aluminum 59Brass 28Cadmium 19Chromium 55Cobalt 16.3Constantin 3.24Copper:Hard drawn 89.5Annealed 100Gold 65Iron:Pure 17.7Cast 2-12Wrought 11.4Lead 7Manganin 3.7Mercury 1.66Molybdenum 33.2Nichrome 1.45Nickel 12-16Nickel silver 5.3(18%)Phosphor bronze 36Platinum 15Silver 106Steel 3-15Tin 13Titanium 5Tungsten 28.9Zinc 28.2
Why copper widely useless conductive material?
Copper is widely used as a conductor for several reasons: >>> It has an extremely low Specific Resistance of 1.682 x 10^-6 ohms/cm. >>> It is relatively cheap compared to some of the alternatives which also have very low resistance, eg, Silver. >>> It is abundant, although its major competitor, Aluminum is more abundant, it has corrosion problems and does not weather well among other things. >>> Copper, when drawn into wire, it has a high Tensile Strength.
Which metal is the poorest conductor of electricity?
Correct Answer= Aluminum( among this 4 conductor)A. Tin C. LeadB. Zinc D. Aluminum
What is the worst conductor of electricity among all metals?
tin, copper, rubber, air, water
