5 Matching questions

  1. Semiconductors
  2. Resistance
  3. Voltage
  4. Electric potential
  5. Current
  1. a is caused by internal friction that slows down the movement of charge through a conductor
  2. b insulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't
  3. c 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. d the rate that electric charges move through a conductor
  5. e The potential energy caused when electric charges have the chance to make an electric force.

5 Multiple choice questions

  1. the force caused by electric charge; opposites attract and like charges repel
  2. all mass is attracted to all mass; height represents potential energy
  3. they NEVER cross
  4. very high resistance
  5. comes from an imbalance of electrons and protons; causes things to attract or repel

5 True/False questions

  1. Insulatorconducts electricity and allows electrons to flow through it (metals, humans, water)

          

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

          

  3. Field lines come out of...negative charges

          

  4. Resistance unitsOhms (Ω say "omega")

          

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