5 Matching questions

  1. Electric charge
  2. Semiconductor (resistance)
  3. A positively charged object will move _______ along a field line
  4. Field lines point to...
  5. Resistance equation
  1. a forward
  2. b medium resistance; resistance can be changed
  3. c comes from an imbalance of electrons and protons; causes things to attract or repel
  4. d V = IR
    Voltage (electric potential) =
    Current x Resistance
  5. e negative charges

5 Multiple choice questions

  1. negative charge carriers; the flow of electrons is what causes current
  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. is caused by internal friction that slows down the movement of charge through a conductor
  4. Amperes (A)
  5. Ohms (Ω say "omega")

5 True/False questions

  1. Current Formulacurrent = charge/time
    I = q/t

          

  2. A negatively charged object will move _______ along a field linebackward

          

  3. Conductor (resistance)low resistance

          

  4. Electric force and distanceStronger at close distances, weaker at long distances

          

  5. MaglevA train that floats above a magnetic track; the tracks are superconductors
