The flashcards below were created by user Jlawrence on FreezingBlue Flashcards.

  1. Electricity:
    A form of energy that results from the interactions of charged particles such as protons or electrons
  2. Static Charge (Static Electricity):
    An electric charge that tends to stay on the surface of an object, rather than flowing away quickly

    i.e. static cling on clothes when they exit the dryer
  3. Charging by Friction:
    A process in which objects made from different materials rub against each other, producing a net static charge on each object

    i.e. rubbing a lumite rod with a plastic bag
  4. Electrostatic Series:
    • A list of materials that have been arranged according to
    • their ability to hold on to electrons (electronegativity)
    • Image Upload 1
  5. Insulator:
    A material through which electron flow is difficult or inhibited

    i.e. rubber
  6. Conductor:
    A material through which electron flow is easy

    i.e. silver
  7. Semiconductor:
    A material through which electron flow is possible, but more difficult

    i.e. silicon
  8. Ground:
    • An object that can supply a very large number of electrons to, or remove a very large number of electrons from, a charged object, thus
    • neutralizing that object
  9. Electroscope:
    A device for detecting the presence of an electric charge

    i.e. metal leaf electroscope, pith ball electroscopeImage Upload 2
  10. Charging by Contact:
    Generating a net charge on a neutral object by touching it with a charged object

    i.e. rubbing your hair with a balloon
  11. Laws of Electric Charges:
    • Laws that describe how two objects interact electrically when
    • one or both are charged

    • 1 -
    • Objects with the same net charge repel
    • 2 -
    • Objects with opposite net charges attract
    • 3 -
    • Charged and neutral objects attract

  12. Electric Field:
    • A property of the space around a charged object, where the effect of its charge can be felt by other objects
    • Image Upload 4
  13. Induced Charge Separation:
    The movement of electrons in a substance, caused by the electric field of a nearby charged object that is not in direct contact with the substance
  14. Ion:
    • A positively or negatively charged atom or group of atoms
    • Image Upload 5
  15. Lightning Rod:
    A metal sphere or point that is attached to the highest part of a building and connected to ground

    i.e. the top of the CN Tower
  16. Electrostatic Precipitator:
    A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas
  17. Van der Graaf Generator:
    A device that accumulated very large chargesImage Upload 6
  18. Radiation Dosimeter:
    A small device that detects and measures radiation exposure
