  2. Semiconductors on the periodic table
  3. Voltage
  4. Semiconductor (resistance)
  5. Maglev
  1. a medium resistance
  2. b 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. c Can be found right on the line between metals and non-metals
  4. d very high resistance
  5. e A train that floats above a magnetic track; the tracks are superconductors

5 Multiple choice questions

  1. negative charge carriers; the flow of electrons is what causes current
  2. conducts electricity and allows electrons to flow through it (metals, humans, water)
  3. zero resistance
  4. Coulomb (C)
  5. do not conduct electricity (rubber, plastic, air, non-metals
