Potential Difference & Electric Current | Week 9

Performance Objectives

By the end of the lesson, students should be able to:

  • Define current and state its formulae
  • Define potential difference
  • Define resistance
  • Electromotive force

An electric current is the time rate of flow of electric charges along a conductor. An electric current is said to coexist when there is a net flow of electric charge through a region.
