Electrical Conductivity Insulators and Conductors

Electrical Conductivity Insulators and Conductors. Insulators. An electrical insulator is a substance that resists or blocks the movement of electrons Insulators can hold a static charge because static charges remain nearly fixed in place Examples of good insulators: plastic, glass, dry wood.

  1. Electrical ConductivityInsulators and Conductors

  2. Insulators An electrical insulator is a substance that resists or blocks the movement of electrons Insulators can hold a static charge because static charges remain nearly fixed in place Examples of good insulators: plastic, glass, dry wood

  3. Conductors An electrical conductor is a substance in which electrons can move freely If a conductor becomes negatively charged with electrons, they move freely along the conductor Examples of good conductors: copper, aluminum

  4. Common Conductors and Insulators
