  1. Electric force
  2. Rule for drawing field lines
  3. Electric potential
  4. Semiconductor (resistance)
  5. Current Formula
  1. a The potential energy caused when electric charges have the chance to make an electric force.
  2. b current = charge/time
    I = q/t
  3. c the force caused by electric charge; opposites attract and like charges repel
  4. d they NEVER cross
  5. e medium resistance

5 Multiple choice questions

  1. Amperes (A)
  2. is caused by internal friction that slows down the movement of charge through a conductor
  3. negative charges
  4. negative charge carriers; the flow of electrons is what causes current
  5. Stronger at close distances, weaker at long distances

5 True/False questions
