Tungsten has high resistance, here is an example, in incandescent light bulb,there is a filament made up of tungsten (metal),when we turn on the switch the electricity flows through the filament making it heat up, NOW what heats up the filament is TUNGSTEN's resistance, HOW AND WHY:

1)Tungten has a high resistance, which mean that more electrons accumulate, as more electrons accumulate it heats up the filament due to resistance, it's just like : when you are cold you rub your hand together to make them warm there is a force called friction that heats up your hands due to the contant rubbing, same is here, when electrons accumulate, they become more resistant, i.e unable to move quickly, so when they can't move easily they began interacting and producing heat, the tungsten metal that is known to have high resistance helps it heat up and light up up as well, if tungsten was not resistant it would melt up at high temperature.

The resistance of a tungsten light bulb is greater than the resistance of a copper wire.

In addition, as the bulb get hotter, the resistance increases, due to the positive resistance to temperature coefficient of the filament.

Copper is second in conduction only to silver, but as silver oxidizes (forms a non-conductive layer) easily, copper is considered the most practical conductor.

As conduction is essentially the opposite of resistance, copper has a lower resistance than iron.

No, copper has a lower resistance to electron flow than aluminum for a given cross sectional area. So if two cables have the same diameter, the copper one will conduct electricity better than aluminum. However, an aluminum cable of the same weight as copper will conduct electricity better than copper. It is for this reason that aluminum is often used for overhead transmission lines, resulting in a lower weight than similar performing copper cable.

Yes, copper has a lower resistance to electron flow compared to aluminum. This means that copper allows electrons to flow more easily through it, leading to better conductivity.

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.


Can you use an aluminium wire instead of copper for a simple electrical circuit?

Yes, you can use an aluminum wire instead of copper for a simple electrical circuit. However, aluminum has higher resistance and is less conductive than copper, so you may need a thicker gauge of aluminum wire to carry the same amount of current. Also, aluminum has a tendency to oxidize more easily than copper, so proper connections and protection against corrosion are important.


Does aluminum heats up faster than copper?

No, copper heats up faster than aluminum because copper has higher thermal conductivity. This means it can transfer heat more efficiently leading to faster heating.


What conducts heat best wood copper or aluminum?

Aluminum conducts heat better than wood and copper. In general, metals like aluminum have higher thermal conductivity compared to materials like wood. This means that aluminum can transfer heat more efficiently than wood or copper.


Is aluminum more conductive than copper?

No, copper is a better conductor of electricity than aluminum. Copper has higher electrical conductivity and lower resistance compared to aluminum. That's why copper wires are commonly used in electrical applications where efficiency is important.

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.


Why do conductors have high resistance?

Conductors have high resistance due to their material properties. Materials with high resistivity like copper or aluminum impede the flow of electrons, causing resistance. Additionally, impurities and defects in the conductor's structure can also contribute to higher resistance.


Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?

The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.


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.


What are factors that affect resistance of electricity?

Factors that affect resistance of electricity include the type of material the wire is made of (e.g. copper vs. aluminum), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance). Temperature also affects resistance, with higher temperatures typically leading to higher resistance.


What affects the resistance of a conductor?

The resistance of a conductor is affected by its length, cross-sectional area, material, and temperature. Longer conductors have higher resistance, while wider conductors have lower resistance. Different materials have different resistivities, influencing resistance. Temperature also affects resistance, usually increasing with higher temperatures.


Does aluminum or copper produce more electricity?

Copper produces more electricity than aluminum due to its higher electrical conductivity. This means that copper allows for better flow of electrical current, resulting in higher electrical output compared to aluminum for the same conditions.
