Electrical conductors are materials with low electrical resistance, or ones that allow for electric current to flow through them. We use conductors to create our circuits by connecting components together with typical conductors, like metal or wire. PCBs need both conductors and insulators in order to function correctly. Conductors provide the path for current to flow through while insulators prevent current from flowing where we do not want it to be.

Common Conductors#

  • Metals, most commonly used are copper, nickel, aluminum, silver, or even gold!
  • Graphite
  • Sea Water
  • Silicon (which is actually a semi-conductor)
