Copper is widely use in the US, it has the second lowest resistivity, behind silver, which is much more expensive making copper the best choice. It resistivity at 20 °C is 1.72×10−8

What is the reaction when aluminum is added to copper sulfate?
The reaction forms aluminum sulfate and frees copper.
Does aluminum or copper conduct the most heat?
copper
What do copper chloride and aluminum form when combined?
copper!
Is copper or aluminum a better heat conductor?
copper is better
What does adding copper to aluminum create?
Aluminum alloy ... a stronger metal.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Which material has a greater resistance aluminum or copper wire?
Aluminium wire has high resistance than Copper.
Aluminum has a specific heat capacity more than twice that of copper Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be?
copper
What kind of marterials have low resistance?
the best conductors with low resistance are silver, copper, gold, aluminum (best to least best)
Why are aluminium and copper used for making electric wires?
Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
What is considered the best conductor silver aluminum glass or silicon?
Silver has a resistance of 1.59x10(-8). Copper has a resistance of 1.72 x 10(-8) Gold has a resistance of 2.44 x 10(-8) Aluminum has a resistance of 2.82 x 10(-8). So the best is Silver then Copper, then Gold, and last Aluminum. (5/07/09)
Of these 4 copper wood silicon aluminum which material would have the highest resistance to the flow of electric current?
silicon
How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
What affects the resistance of a conductor?
The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7
Which is lighter-copper or aluminum?
Aluminum
