Copper is more electrically conductive than aluminum (this is because aluminum forms a monomolecular layer of non-conductive aluminum oxide on its surface).

Is a coper penny a conductor or insulator?
A copper penny (is more an alloy than pure copper) is a conductor of electricity.
Why are copper wires used as the connecting wires?
Copper is a metal and as such it can conduct electricity very well. Additionally, copper is a very good conductor off heat when compared to the more abundant metals such as aluminium.
What material allows electricity to pass through it easily?
Metals. Copper has one of the lowest resistivities. Resistivity is a measure of how easily electricity flows - the lower the better the electricity flows. Silver has an even lower resistivity but obviously it is more expensive. Aluminium is also good but it oxidises so would not be as good a conductor as copper which resists oxidation.
What is the other alternative for copper wire?
Wires are made of many metals (and even non-metals). Field telephone wires for military use are steel. The Electric Company uses more aluminum than copper. Silver is the best conductor. Gold is used to wire integrated circuits because it does not corrode.
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.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
Is aluminum electrically conductive?
Yes...all metals are will conduct electricity.
What is a common metal used in wires to conduct electricity?
copper or even more often brass Copper and aluminum are used in house wiring. Aluminum is typically used in the entrance cable and copper for everything past the breaker panel. Aluminum was used for house wiring a few decades ago but it was linked to numerous electrical fires because the connections would weaken over time.
Is silver metal a good conductor of electricity?
Yes it is... the only reason it is not used as much as it would be is because it is more expensive than copper, steel, and aluminum.
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
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 characteristic of copper and aluminum causes the to be good conductors what is the effect?
They are both metals. The effect is that copper is more safer than aluminum. From Leah :)
How to transport and store copper clad aluminum?
In the process of transporting copper-clad aluminum, you should pay more attention, because if it is not transported properly, it will cause damage to the copper-clad aluminum, and the impact will be relatively large. We will bring you more exciting information in the future.
What metallic element is used to make pipes electrical wire and pots and pans?
Most cookware uses aluminum as a thermal conductor. - - - - - The element that conducts heat the best is Copper. The finest pans are made from it, but they must be lined with tin before use because bare copper reacts with acidic foods.
Is silver a better conductor of electricity than copper?
no copper is more conductive YES, silver is more conductive than copper.
