5 True/False questions

  1. A positively charged object will move _______ along a field linebackward

          

  2. Electric potentialthe force caused by electric charge; opposites attract and like charges repel

          

  3. Resistanceis caused by internal friction that slows down the movement of charge through a conductor

          

  4. Conductor (resistance)medium resistance; resistance can be changed
