Electrical Conductors

Electrical conductors are materials that easily allow the flow of electric current. This is because they have loosely bound electrons in their outer shells that can move freely throughout the material. Metals are the most common type of electrical conductor, but other materials such as electrolytes and semiconductors can also conduct electricity.

Here are some of the properties of electrical conductors:

  • High electrical conductivity: This means that they can easily carry electric current.
  • Low electrical resistance: This is the opposition to the flow of electric current.
  • Ductility: They can be easily drawn into thin wires.
  • Malleability: They can be easily hammered into thin sheets.


Electric al conduc tors are used in a wide variety of applications, including:

  • E lectrical wiring: Electrical conductors are used to carry electricity from power sources to electrical devices.
  • Busbars: Busbars are large conductors that are used to distribute electricity within a power system.
  • E lectrical cables: Electrical cables are bundles of insulated conductors that are used to transmit electricity over long distances.
  • Printed circuit boards (PCBs): PCBs are thin boards made of insulating material with copper tracks that act as electrical conductors. They are used to connect electronic components together.

The most common electri cal conduct ors are metals, such as copper, aluminum, silver, gold, and steel. Copper is the most widely used electric al condu ctor because it has a high electrical conductivity and is relatively inexpensive. Aluminum is another common electri cal condu ctor because it is lighter than copper and is also relatively inexpensive. Silver is the best ele ctrical conduc tor, but it is too expensive to be used for most applications. Gold is a good electri cal condu ctor, but it is also very expensive. Steel is not as good a conductor as copper or aluminum, but it is often used for applications where strength is important.
