  1. Conductor (resistance)
  2. A negatively charged object will move _______ along a field line
  3. Resistance equation
  4. Maglev
  5. Resistance units
  1. a low resistance
  2. b V = IR
    Voltage (electric potential) =
    Current x Resistance
  3. c A train that floats above a magnetic track; the tracks are superconductors
  4. d backward
  5. e Ohms (Ω say "omega")

5 Multiple choice questions

  1. they NEVER cross
  2. 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)
  3. insulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't
  4. forward
  5. draw more field lines

5 True/False questions

  1. Semiconductor (resistance)low resistance


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


  3. Current Formulathe rate that electric charges move through a conductor


  4. Semiconductors on the periodic tableCan be found right on the line between metals and non-metals


  5. Electric potentialThe potential energy caused when electric charges have the chance to make an electric force; also called VOLTAGE
