Verified Answer
Materials which allow the passage of electric current are known as____...
Conductors are materials(mostly metals), which freely allow the passage of electrons through it. If electrons can flow freely through a material, it implies that even current can flow freely through that material since current is the rate of flow of electrons.

Conductors: Materials that allow the passage of electric current

Conductors are materials that have the ability to allow the flow of electric current through them. These materials have a high number of free electrons that are loosely bound to their atomic structure. When an electric potential difference is applied across a conductor, these free electrons are able to move freely through the material.

Characteristics of Conductors:

1. High Electrical Conductivity: Conductors have a high electrical conductivity, which means they offer low resistance to the flow of electric current. This is due to the presence of a large number of free electrons that can easily move through the material.

2. Low Resistivity: Conductors have low resistivity, which is a measure of the material's ability to resist the flow of electric current. Low resistivity allows for efficient transmission of electric current through the material.

3. Good Heat Conductivity: Conductors also have good heat conductivity, which means they can effectively transfer heat. This property is useful in applications where heat dissipation is important, such as in electrical wiring or heat sinks.

4. Metallic Properties: Most conductors are metals, which exhibit metallic properties such as malleability, ductility, and shiny appearance. These properties are a result of the metallic bonding between atoms in the material.

5. Low Voltage Drop: Conductors have a low voltage drop when electric current flows through them. This means that there is minimal loss of voltage along the length of the conductor, allowing for efficient power transmission.

Examples of Conductors:

1. Copper: Copper is one of the most commonly used conductors due to its high electrical conductivity, low resistivity, and good heat conductivity.

2. Aluminum: Aluminum is another widely used conductor, particularly in power transmission lines, due to its relatively high electrical conductivity and lower cost compared to copper.

3. Silver: Silver is the most conductive material and is used in specialized applications where high conductivity is required.

4. Gold: Gold is also a highly conductive material and is commonly used in electronic components and connections.

5. Iron and steel: Although not as conductive as copper or aluminum, iron and steel are still used as conductors in certain applications, such as in power distribution systems.

In conclusion, conductors are materials that allow the passage of electric current due to their high electrical conductivity and low resistivity. Examples of conductors include copper, aluminum, silver, gold, iron, and steel.
