5 Matching questions

  1. A positively charged object will move _______ along a field line
  2. Voltage
  3. Conductor (resistance)
  4. Insulator
  5. Resistance equation
  1. a forward
  2. b low resistance
  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 V = IR
    Voltage (electric potential) =
    Current x Resistance
  5. e do not conduct electricity (rubber, plastic, air, non-metals

5 Multiple choice questions

  1. A train that floats above a magnetic track; the tracks are superconductors
  2. zero resistance
  3. is caused by internal friction that slows down the movement of charge through a conductor
  4. positive charges
  5. all mass is attracted to all mass; height represents potential energy

5 True/False questions

  1. Potential energycomes from an imbalance of electrons and protons; causes things to attract or repel

          

  2. Semiconductorsinsulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't

          

  3. Current Formulathe rate that electric charges move through a conductor

          

  4. Conductorinsulators in their natural state, but can be manipulated so that sometimes they conduct, and sometimes they don't

          

  5. Electronsthe force caused by electric charge; opposites attract and like charges repel
