Electrical Engineering

Electrical engineers, abbreviated as EE, design, develop, test, and supervise the manufacturing of electrical equipment.  Electrical & Electronic engineers design things such as power systems, electronics/microelectronics, signal processing, instrumentation & control systems, computers, and computer networks.

Electric Wire Materials

  • Copper electrical wire - Copper (Cu) is considered the standard in wiring. Most homes and appliances use copper for two reasons. It is easy to mold or bend and it is a good conductor. Copper is rather easy to come by but not as easy as other conductor metals.
  • Aluminum electrical wire - Aluminum (Al) is also easy to mold and bend but less of a conductor than copper. If you decide to use aluminum wire that will carry the same amount of electricity as a copper wire, the wire needs to have a larger diameter. Since aluminum is more abundant than copper, it makes it the cheaper of the two.
  • Silver electrical wire - Silver (Ag) is the best conductor of electricity for high temperatures. However, it is hard to bend and expensive.
  • Alloys in electrical wire - In manufacturing, an alloy may sometimes be used. Aluminum and copper can be used for cost and conductibility.
