5 Matching questions

  1. Voltage
  2. When charges are stronger... (what do we do with field lines?)
  3. Superconductor (resistance)
  4. Conductor (resistance)
  5. Conductor
  1. a the difference in electrical potential energy between two places in a circuit; tells you which way charges want to move and how badly (like a map of where charges want to go)
  2. b zero resistance
  3. c draw more field lines
  4. d conducts electricity and allows electrons to flow through it (metals, humans, water)
  5. e low resistance

5 Multiple choice questions

  1. the force caused by electric charge; opposites attract and like charges repel
  2. The potential energy caused when electric charges have the chance to make an electric force; also called VOLTAGE
  3. current = charge/time
    I = q/t
  4. Ohms (Ω say "omega")
  5. do not conduct electricity (rubber, plastic, air, non-metals

5 True/False questions

  1. Semiconductor (resistance)low resistance

          

  2. Rule for drawing field lineszero resistance

          

  3. Currentthe rate that electric charges move through a conductor

          

  4. GravityA train that floats above a magnetic track; the tracks are superconductors

          

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