  1. Resistance
  2. Units for current
  3. Current Formula
  4. Resistance equation
  5. Units for charge
  1. a V = IR
    Voltage (electric potential) =
    Current x Resistance
  2. b current = charge/time
    I = q/t
  3. c Amperes (A)
  4. d is caused by internal friction that slows down the movement of charge through a conductor
  5. e Coulomb (C)

5 Multiple choice questions

  1. 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)
  2. all mass is attracted to all mass; height represents potential energy
  3. draw more field lines
  4. negative charge carriers; the flow of electrons is what causes current
  5. Can be found right on the line between metals and non-metals

5 True/False questions

  1. Conductordo not conduct electricity (rubber, plastic, air, non-metals


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


  3. A positively charged object will move _______ along a field lineforward


  4. Semiconductorsconducts electricity and allows electrons to flow through it (metals, humans, water)


  5. Superconductor (resistance)zero resistance
