5 Matching questions

  1. Potential energy
  2. Resistance units
  3. Conductor
  4. Semiconductors
  5. Gravity
  1. a conducts electricity and allows electrons to flow through it (metals, humans, water)
  2. b Ohms (Ω say "omega")
  3. c the capacity to do work
  4. d insulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't
  5. e all mass is attracted to all mass; height represents potential energy

5 Multiple choice questions

  1. low resistance
  2. comes from an imbalance of electrons and protons; causes things to attract or repel
  3. the rate that electric charges move through a conductor
  4. medium resistance
  5. Coulomb (C)

5 True/False questions

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

          

  2. Units for currentCoulomb (C)

          

  3. Voltagethe 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. Electric forcethe force caused by electric charge; opposites attract and like charges repel

          

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