Understanding Goals

Subject Matter

  • Some materials allow electrons to move more freely along them than others. This has to do with the nature of their bonds.
  • Materials that allow electrons to move freely are called conductors. Materials that do not allow electrons to move easily are called insulators.

Causality

  • Material types affect current flow, comprising a form of passive causality.
