Topics

Main Topics

  • Resistivity
  • Resistance

Related Topics

Sample Learning Goals

  • As you change either the resistivity
  • length
  • or area of the resistor
  • the resistance changes. Will increasing or decreasing each of these three values make the resistance correspondingly increase or decrease? Why?
