  5. e forward

5 Multiple choice questions

  1. current = charge/time
    I = q/t
  2. backward
  3. 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)
  4. insulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't
  5. Coulomb (C)

5 True/False questions

  1. Superconductor (resistance)medium resistance; resistance can be changed


  2. When charges are stronger... (what do we do with field lines?)draw more field lines


  3. Resistance equationOhms (Ω say "omega")


  4. Insulator (resistance)very high resistance


  5. Currentthe rate that electric charges move through a conductor
