Internal Resistance addresses the following learning objectives:

  • Define electromotive force (EMF) and potential difference (pd) of a simple DC circuit;
  • Appreciate the existence of internal resistance of sources and understand its consequences on external circuits;
  • Understand and use the terms, ?Lost Volts? and ?Terminal Potential Difference?;
  • Recall and use the equation: E=V+Ir;
  • Conduct an investigation to determine the EMF and internal resistance of an electric cell.
