Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
Does aluminum have lower resistance than copper?
No, copper has lower resistance than aluminum. Aluminum is a less conductive material compared to copper, which means it has higher resistance to the flow of electricity.
Do motorcycle battery cables have less resistance than automotive battery cables?
No...the resistance of any cable is goverened by it`s size+length, and the metal it`s made of.........eg. aluminum has more restance than copper
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
Why is copper used for electrical wiring instead of iron?
Copper wires conduct electricity much better than iron. This is because electric current passes through copper with very less resistance. it is also more ductile and malleable.
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
What resistance of a connecting wire is less than the resistance of a resistor?
The resistance of a connecting wire that is less than the resistance of a resistor would depend on the materials and dimensions of the wire and resistor. Generally, most connecting wires have very low resistance compared to resistors. Copper wires, for example, have low resistance and are commonly used for connecting circuits.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper has lower electrical resistance than aluminum, allowing for less power loss during transmission. Copper also has better thermal conductivity and is more durable than aluminum, leading to a longer lifespan for transmission lines. However, aluminum is lighter and more cost-effective than copper, making it a popular choice for long-distance transmission lines.
Is copper more reactive than tin?
No, copper is less reactive than tin. Tin reacts readily with acids, but copper is less reactive and tends to form a protective layer of oxide on its surface, making it more resistant to corrosion.
What copper wire would have the highest resistance?
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
